A. During aerobic respiration, cells take in O2 (Oxygen is an input of cellular respiration) and release CO2, H2O and ATP.
Cellular respiration equation (THIS IS VERY USEFUL :) ):
C6H12O6 (Glucose) + O2 (Oxygen) = 6CO2 (Carbon dioxide) + 6H2O (water) + 36-38 ATP (energy)
NOTE: Inputs are the things going in, outputs are the things being produced.
WHY THE OTHER ANSWERS ARE WRONG:
B. Not B because it mentions the process of fermentation which is anaerobic.
C. Not C because insulin has nothing to do with cellular respiration in particular but rather blood glucose level homeostasis
D. Not D because although it is partially 'correct', the actual wording (inhaled /exhaled) is incorrect as H2O is produced not exhaled. ATP energy is also produced.
I hope this helps
gymnoseperms meaning "naked seeds" are a diverse group of seed plants and are paraphyletic. paraphyletic groups are those in which not all members are descendants of a single common ancestor. gymnoseperm seeds are not enclosed in an ovary; rather, they exposed in cones or modified leaves
Mitochondria produce ATP through process of cellular respiration—specifically, aerobic respiration, which requires oxygen. The citric acid cycle, or Krebs cycle, takes place in the mitochondria. This cycle involves the oxidation of pyruvate, which comes from glucose, to form the molecule acetyl-CoA. Acetyl-CoA is in turn oxidized and ATP is produced.
