Question

question 15. during exercise, muscle cells consume large amounts of energy. which organelles increase their activity in muscle cells during exercise to make more energy available? a. nuclei b. ribosomes c. mitochondria d. golgi complexes

Explanation:

Mitochondria are the power - houses of the cell, responsible for producing energy in the form of ATP through cellular respiration. During exercise, muscle cells need more energy, and mitochondria increase their activity to meet this demand. Nuclei contain genetic material and are involved in cell division and regulation of gene expression, not energy production. Ribosomes are involved in protein synthesis. Golgi complexes are involved in modifying, sorting, and packaging proteins and lipids.

Answer:

C. Mitochondria
