What happens to the carbon dioxide produced by cellular respiration? a. it is reused by the body as glucose b. it is excreted from the body as solid waste c. it is excreted from the body as liquid waste d. it is breathed out of the body by the lungs

The right answer is D

Carbon dioxide (CO2) accounts for 77% of human-induced greenhouse gas (GHG) emissions. It results mainly from the burning of fossil fuels and the change in land use (agriculture and deforestation) and in a small proportion of the breathing of living beings.

Respiration is gaseous exchange resulting from inhalation and expiration of the air (more precisely, CO2 carbon dioxide release and oxygen O2 absorption) and cellular respiration that allows, by degrading glucose through oxygen, to obtain energy.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
