Answer:
The answer of ist question FADH2,NADH 2nd question O2 3rd question NAD+,FAD,H2O,ATP.
Explanation:
Ist answer
During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.
2nd answer
During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.
3rd answer
The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.
The correct answer is 'adrenarche'. This is also the period of early sexual maturation in humans and other higher primates. This period is associated with the development of pubic hair, body odor and acne. The adrenal cortex secretes higher levels of androgens. The development of a new zone of the adrenal cortex, called the zona reticularis, occurs during this period.
In the dark reactions, also called the Calvin Cycle, the NADPH and ATP from the light reactions are used to make glucose. A monosaccharide sugar that is commonly used in the body of an organism.
