Photosynthesis, ATP and Respiration Review

Which of the following best describes what's happening during photosynthesis?

• Chemical energy is converted into a different type of chemical energy within the chloroplast.

• Within the chloroplast of plant cells, light energy is converted into chemical energy and stored in a glucose molecule.

• Within the mitochondria, sugar is broken down into usable forms of energy called ATP.

• This is the process where plants consume glucose molecules created by animals within their mitochondria.
