After glycolysis happens in the cytoplasm, where do the pyruvate molecules that were made from the food go for the next step in the cellular respiration process?

the nucleus
the golgi apparatus
they remain in the cytoplasm
the mitochondria

Mitochondria

Explanation:

Pyruvic acid enters the mitochondria where in the presence of oxygen it is converted into acetyl coenzyme A. Acetyl coenzyme A joins the Krebs cycle in which it is broken down to carbon dioxide, water and energy which is used to produce ATP. ATP is a complex organic molecule.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
