They are made from igneous, metamorphic and sedimentary rock.
The answer is NAD+.
NAD+ is the primary oxidizing agent in the glycolytic pathway. Oxidizing agents gain electrons and thus, they are reduced in a reaction. In the glycolytic pathway, NAD+ server the oxidizing agent. It accepts electrons from the molecules, such as some intermediates of the glycolytic pathway. As the result, it is reduced to NADH which can serve in some reactions as a reducing agent.
<span>Three fossil fuels are, natural gas, coal and oil
I guess what could differentiate them is that: </span>Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits are turned into coal. Whereas Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor and gas like oil, it is formed from the remains of marine microorganisms.<span>
So the difference could be how they are formed</span>
Answer:
When the molecules are too large.
Explanation:
Facilitated diffusion refers to the passive transport of substances down the concentration gradient via specific transport proteins present in the membrane. The large, polar, charged substances and ions cannot pass through the small spaces present between hydrophobic tails of membrane phospholipids. The transport proteins transport these substances in energy independent manner.
