Answer:
The correct answer is a. They release their secretions into the blood.
Explanation:
Endocrine glands are responsible for producing/secreting hormones and releasing them directly into the blood from where they travel to tissues and organs throughout the body. Some examples of endocrine glands are the pituitary gland (it regulates homeostasis), the thyroid gland (It helps to regulate growth and metabolism) and the adrenal glands (they perform different functions at the endocrine and nervous level).
Answer:
b. Complex II
Explanation:
The electron transport chain is a sequential series of proteins located in the inner membrane of the mitochondria that act to transfer electrons from different members of the transport chain in a series of redox reactions, which is coupled to the movement of protons (H+) across the membrane. Complex I (also called NADH dehydrogenase or NADH- CoQ reductase) accepts electrons from NADH and passes them to Complex III (also known as coenzyme Q reductase), which also receives electrons from Complex II (succinate coenzyme Q reductase). Ubiquinone (Coenzyme Q) accepts electrons from both complex I and complex II and transfer them to complex III. From complex III electrons pass to complex IV through cytochrome c oxidase and finally to molecular oxygen (O2, the final electron acceptor). In consequence, Complex I and Complex II are linked by different pathways to Complex III, thereby it is expected that Complex II remains unaffected by a mutation in Complex I.
