A glucose molecule is a monomer of starch and cellulose
B.
Photosynthesis produces energy which is used during respiration to break down carbohydrates like starch into more usable forms like glucose
Processes that are most important to human life are oxygen, required for cellular respiration, and glucose, a form of sugar that releases energy during cellular respiration.
The cosmological principle makes assumptions that provide scientific guidelines to enable its study.
