Question

List ALL of the substrate-level phosphorylation steps in

cellular respiration and the enzymes that perform these SP steps.

For your answer, use this format:

reactant. poroduct . enzyme

Cellular Respiration = Theoretical Energy
Glucose contains 686 to 720 kcal/mol
• ATP contains 7.3 kcal/mol
36 ATP harvested from each molecule of glucose
2 from glycolysis – substrate level phosphorylation
2 from Kreb's cycle – converted from GTP (not done by all cells)
32 from the ETC & NADH/FADH2
note: NADH in the cytosol is only worth 2ATP; NADH in the mitochondria are
worth 3 ATP
36 moles of ATP × 7.3 kcal/mol = 263 kcal trapped as ATP
efficiency : 263/686 = 36 to 38% efficiency in converting the
potential energy of glucose into chemical energy

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
