Question

Which statement best describes energy release in cellular respiration? (1 point)
A stored chemical energy can be used immediately and is released in the cytoplasm
B stored chemical energy can be used immediately and is released in the mitochondria
C stored chemical energy is broken down and released in the cytoplasm
D stored chemical energy is broken down and released in the mitochondria

Answer 1

The statement that best describes energy release in cellular respiration is:

**D stored chemical energy is broken down and released in the mitochondria.**

During cellular respiration, glucose (a stored chemical energy source) is broken down in the mitochondria, producing ATP, which cells use as energy.
