During which phase of cellular respiration is carbon dioxide released?
Glycolysis
Electron transport chain
Substrate level phosphorylation
Krebs cycle
Answer explanation
Carbon dioxide is released during the Krebs Cycle, also known as the citric acid cycle or TCA cycle, which occurs after glycolysis and before the electron transport chain.

Cellular respiration is an example of which type of metabolism?
Catabolism
Anabolism
Denaturation
Answer explanation

Biologically speaking, the purpose of fermentation is
to recycle NAD+ and FADH
to hydrolyze ATP
to regenerate ATP
to reduce NAD+ and FADH
Answer explanation
Biologically speaking, the purpose of fermentation is to produce energy (ATP) in the absence of oxygen by breaking down glucose or other organic molecules through a process that involves the partial oxidation of the substrate and the reduction of an electron acceptor, such as pyruvate or acetaldehyde.
