Question

1. where does cellular respiration occur?

a. vacuole
b. ribosome
c. chloroplast
d. mitochondria
e. endoplasmic reticulum

Explanation:

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP). Mitochondria are known as the "powerhouses" of the cell because they produce ATP through cellular respiration. Vacuoles store substances, ribosomes synthesize proteins, chloroplasts are for photosynthesis, and the endoplasmic reticulum is involved in protein and lipid synthesis.

D. Mitochondria
