Question

use the diagram above to answer the next question. which of the following processes requires one of the products of this organelle? i secretion of neurotransmitters at a synapse ii movement of iodine ions into the thyroid gland iii movement of sodium ions across the cell membrane in the kidney tubules select one: a. i and ii only b. i and iii only c. i, ii, and iii d. ii and iii

Explanation:

Step1: Identify the organelle

The organelle is a mitochondrion which produces ATP through cellular respiration.

Step2: Analyze process I

Secretion of neurotransmitters at a synapse requires ATP for exocytosis.

Step3: Analyze process II

Movement of iodine ions into the thyroid gland is active - transport which requires ATP.

Step4: Analyze process III

Movement of sodium ions across the cell - membrane in the kidney tubules is active - transport and requires ATP.

Answer:

c. I, II, and III
