Oxygen is an element in the sixth group of the periodic table. This means it contains 6 electrons in its valence shell. Therefore, to complete its octet, it will prefer to gain two electrons rather than to donate 6. This is why its valency is -2. The relatively easy to achieve octet makes Oxygen a reactive element.
[ Equilibrium / Diffusion ] is the simplest type of passive transport. 7. The diffusion of water through a selectively permeable membrane is called [ osmosis / diffusion ].
Polar bonds are when negatives and positives are attracted to eachother
The answer is A. It is gotten from eating food.
Answer:
NADPH is an activated carrier molecule that is used primarily by plants (NOT TRUE)
Explanation:
NADPH is indeed an electron carrier molecule that participates in various metabolic (anabolic) reactions carried out by plants, but it also participates actively in metabolic (anabolic) reactions carried out in animal tissues, this means that it is used by the cells of the human body as well.
A very important metabolic process in which the NADPH is produced is during the glucose 6-phosphate oxidation into phosphate pentoses through the pentose phosphate pathway. In this process NADP+ is the main electron acceptor, so when it is reduced it produces NADPH. <u>This NADPH is very important for the synthesis of fatty acids, cholesterol and various steroid hormones.</u>
