Before acetyl CoA can be found during respiration, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, pyruvate undergoes decarboxylation, catalyzed by the pyruvate dehydrogenase complex, which converts it into acetyl CoA while releasing carbon dioxide and generating NADH. This conversion is essential for the subsequent entry of acetyl CoA into the Krebs cycle for further energy production.
Glycolysis
Before acetyl CoA can be formed during respiration, pyruvate must be produced from glycolysis, which occurs in the cytoplasm. This pyruvate is then transported into the mitochondria, where it undergoes decarboxylation by the pyruvate dehydrogenase complex. During this process, one carbon atom is removed from pyruvate as carbon dioxide, and the remaining two-carbon fragment is combined with coenzyme A to form acetyl CoA. Additionally, NAD+ is reduced to NADH in this reaction.

Immediately after pyruvate enters the mitochondrion, it is converted into acetyl-CoA through a process called pyruvate decarboxylation. This reaction is catalyzed by the pyruvate dehydrogenase complex, which also produces carbon dioxide as a byproduct and reduces NAD+ to NADH. Acetyl-CoA then enters the citric acid cycle (Krebs cycle) to continue cellular respiration and energy production.
Glycolysis
Before acetyl CoA can be formed during respiration, glucose is broken down through glycolysis to produce pyruvate. Pyruvate is then converted to acetyl CoA in the mitochondrial matrix by the enzyme pyruvate dehydrogenase complex. This process generates NADH and CO2 as byproducts.

Cellular respiration is the process by which a living creature's cells turns glucose.
The carbon dioxide produced during respiration during day time is used up for photosynthesis. However during night, the rate of respiration exceeds the rate of photosynthesis due to unavailability of adequate sunlight.
Plant and animal cells wouldn't MAke ATP in cellular respiration.
They can happen before, after or during, even not at all.
the glucose molecules must break down into two smaller molecules
Respiration can happen without sunlight, but photosynthesis cannot.
Nothing! as we are aerobes and need oxygen for respiration.
a person needs oxygen and glucose for respiration
