Describe the differences between substrate-level phosphorylation and chemiosmotic (oxidative) phosphorylation as mechanisms of ATP formation. Where in a prokaryotic cell does each occur? What are the substrates that are used to form ATP? What is the source of energy for ATP synthesis?
Which of the following is correct? O Most of the ATP are produced by substrate-level phosphorylation. O Glycolysis relies on substrate-level oxidation for the four ATP produced in this pathway. O Most ATP from cellular respiration are produced directly in the citric acid (Krebs) cycle. Each FADH2 yields about 1.5 ATP via oxidative phosphorylation. Submit Request Answer
Explain the chemiosmotic mechanism of ATP generation. How does oxidative phosphorylation compare with substrate level phosphorylation found in glycolysis and the Kreb’s cycle?
Explain the chemiosmotic mechanism of ATP generation. How does oxidative phosphorylation compare with substrate level phosphorylation found in glycolysis and th e Kreb’s cycle?
Where do the following occur in a cell? a) Glycolysis b) Citric Acid Cycle c) Oxidative Phosphorylation d) Carbon Fixation
Which of the following is NOT correct about substrate level phosphorylation and oxidative phosphorylation? A. oxidative phosphorylation occurs absence of molecular oxygen B. substrate level phosphorylations use ADP as a substrate C. substrate level phosphorylations requires molecular oxygen D. both substrate level phosphorylation and oxidative phosphorylation produce ATP as a product E. substrate level phosphorylations only take place in the mitochondria I believe the answer is D, please verify & explain. Thank you
