1. The energy stored in glucose is converted into a usable form, the energy source of all cells, triphosphate, or . 2. The equation for respiration is:
+ O2 > CO2 + H2O +
3. Because oxygen is used to produce ATP, this is referred to as an process.
4. The release of energy cannot occur all at once. Too much would be released inside the cells. Instead, the release of energy occurs in a series of small steps.
5. Plants do photosynthesis only when there is light, during the day. So, they take in only during the day. But, they do respiration all the time, 24 hours a day. All living things do cellular respiration all the time or they are not alive. So, all organisms use , all the time.
