If you cut your knee, pus, which is caused by the death of macrophages may form.
Cellular respiration would be:
b. glucose + oxygen --> carbon dioxide + water + ATP.
More specifically, the equation for cellular respiration is:
C6H1206 + 602 --> 6CO2 + 6H20 + ATP
Also, it may help you remember the equation by noticing that it is the exact opposite of photosynthesis :) Hope this helped!
Autotrophic behaviour depends on the ability of the cell to carry out photosynthetic or aerobic respiratory metabolism, which are the only processes able to deliver sufficient energy to maintain carbon fixation. The Calvin cycle is used by bacteria to synthesize organic compounds.
