Answer :B. They are used to reduce molecular oxygen to water in the electron transport chain.
Explanation:
<u>oxygen is the final electron acceptor in the electron transport chain(ETC) of cellular respiration.</u>
If electrons were not accepted by oxygen, the concentration gradients which drives Co-enzymes NADH and FADH2 from the citric acid cycle to the matrix of mitochondrial for ETC will seize; proton pumps across the mitochondrial intramembranes will not exist.
<u>Therefore no proton gradient for ATPase synthase to synthesise ATP from ADP. Thus no ETC</u>
conclusively, oxygen must be reduced by the electron.
Note:
option D; is near to the correct option, but it is wrong because, it is the energy supplied by the proton gradient that drives the phosphorylation of ADP to ATP, not the electron.The electron only provided the potential energy for the pumping of the protons, but not for the direct phosphorylation
Answer:
A compound is the answer
Explanation:
solution = liquid and something that dissolves
homogeneous mixture = mixture is literally in the name so no
compound = CORRECT ANSWER
heterogeneous mixture = mixture is literally in the name so no
Answer:
DNA is located in the nucleus, but can also be found in other cell structures called mitochondria. Since the nucleus is so small, the DNA needs to be tightly packaged into bundles known as chromosomes.
Explanation:
Answer is;
The animal population in the environment will increase.
This is because the grass is the main producer in a habitat. Its plentifulness directly influences that of the consumers up the food web. Increase in grass population means reduced competition for primary consumers and their population will therefore increase. This will also reduce competition for secondary consumers and tertiary consumers up the chain.
