Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Komponen Penyusun / Struktur Kimiawi Sel (Biologi)



Setelah anda memahami mengenai “Sel :Pengertian, Teori Dan Sejarah Tentang Sel” tentu anda akan sangat gampang untuk memahami materi ihwal “Komponen Penyusun / Struktur Kimiawi Sel (Biologi)” ini. Berikut uraiannya.

 tentu anda akan sangat gampang untuk memahami materi ihwal  Komponen Penyusun / Struktur Kimiawi Sel (Biologi)
Komponen Penyusun / Struktur Kimiawi Sel (Biologi)

Setiap sel disusun oleh bahan-bahan organik dan anorganik. Dimana materi organik mencakup : karbohidrat, protein dan lemak (lipid). Dan materi anorganiknya mencakup : air, gas, dan garam-garam mineral. Dimana setiap komponen tersebut mempunyai tugas dan fungsi masing-masing yang saling mendukung antara satu dengan yang lainnya.

A. Bahan – Bahan Anorganik

1. Air

Air merupakan salah salah satu unsur kimiawi sel yang terbesar, penyusun protoplasma (95 %). Protoplasma merupakan adonan materi hidup dalam sel yang terdiri dari cairan koloid adonan dari bahan-bahan organik dan organel-organel sel yang biasanya tidak termasuk vakuola yang besar, dan protoplasma dilindungi oleh membran plasma. Membran plasma juga merupakan bab dari protoplasma.

Pada sel, air mempunyai banyak tugas diantaranaya sebagai transpotasi nutrisi antar sel, sebagai transportasi dari hasil sekresi dan ekresi, sebagai pelarut bahan-bahan organik, berperan dalam reaksi-reaksi biokimia sel, menjaga ph sel dan juga bisa dalam menghantarkan maupun dalam mengabsorbsi panas, sehingga air sangat penting pada termoregulasi atau pengatur suhu.

2. Gas-gas

Diantara unsur kimiawi golongan gas dalam sel yaitu nitrogen (N), ammonia (NH3), oksigen (O2) dan karbondioksida (CO2). Unsur nitrogen dalam sel tidak terpakai namun sanggup berikatan dengan sel dalam bentuk ion nitrat. Ammonia (NH3) merupakan gas hasil dari sisa metabolisme protein pada sel-sel hewan, ammonia bersifat toksik (racun) sehingga harus dieliminasi (dikeluarkan) dari badan semoga tidak mengakibatkan keracunan bagi tubuh. 

Oksigen bisa didapat dari sisa sintesis karbohidrat oleh tumbuhan melalui fotosintesis, dimana diadalam sel oksigen berperan sebagai oksidasi zat-zat masakan untuk memperoleh energi. Sisa metabolisme zat-zat masakan menghasilkan karbondioksida, dimana didalam badan binatang karbohidrat berperan dalam pembentukan ion CO3- dan HCO3-. Dan bagi tumbuhan karbondioksida berperan sebagai materi mentah bersama air untuk menyintesis karbohidrat, dan sisa dari sintesis karbohidrat bisa menghasilkan oksigen.

3. Garam-garam Mineral

Garam-garam  mineral yang terdapat dalam sel yaitu pada protoplasmanya berada dalam bentuk ion-ion, ion positive maupun negative. Berasal dari garam (NaCl, CaSO4, MgCl2, MgCl2, KH2PO4), asam (HCl, HNO3) , basa ( NaOH, KOH), kation ( H+, NH4+, Ca2+, K+, Na+), anion (OH-, HCO3-, Cl-, NO3-).


B. Bahan-Bahan Organik

Bahan organik didalam sel terdiri atas karbohidrat, protein dan lemak.

1. Karbohidrat

Karbohidrat adalah kelompok senyawa organik yang terdiri dari unsur H,C,O. biasanya tersideia dalam bentuk gula sederhana monosakarida (glukosa dan fruktosa) dimana monosakarida tidak sanggup dihidrolisis lagi menjadi molekul yang lebih kecil lagi 2 molekul sederhana , disakarida (maltosa) dimana disakarida merupakan gabungan dua unit sakarida dan jikalau dihidrolisis maka disakarida akan berkembang menjadi 2 monosakarida.  Dan beberapa molekul monosakarida bisa bergabung dan membentuk polisakarida ( pektin, lignin, kitin, zat pati, amilum dan selulosa). Dan fungsi utama dari karbohidrat yaitu sebagai sumber energi.

2. Protein

Protein tersusun atas unsur C,H,O dan juga unsur N dan kadang kala ditambah dengan unsur Fe dan S pada beberapa jenis protein. Secara sederhananya protein yaitu ikatan dari polimer asam amino yang membentuk ikatan bersama yang disebut peptida dan kemudian membentuk ikatan peptida yang disebut polipeptida. Satu protein terdiri dari satu atau lebih ikatan polipeptida. Diantara fungsi protein yaitu membentuk organel sel, selaput sel, senyawa lain, menggantikan atau memperbaiki jaringan yang rusak dll. 

3. Lemak (Lipid)

Lemak disusun oleh unsur karbon (C), Hidrogen (H) dan Oksigen (O). Senyawa utama yang membentuk lemak yaitu asam lemak dan gliserol( homogen alkohol). Diantara fungsi lemak yaitu sebagai cadangan energi, mengatur peredaran lemak, sebagai struktur kimiawi membran sel bersama dengan karbohidrat dan protein. Sifat lemak tidak bisa larut dalam air dan bisa larut dengan memakai pelarut organik menyerupai eter dan etanol dll.
