QUESTIONS 0.1 points Save Answer What is chemiosmosis? ATP synthase rotating to add a phosphate to ADP - ATP All of these contribute to chemiosmosis Proton gradient in the inner membrane space causing protons to enter into the matrix causing ATP synthase to convert ADP to ATP An electrical gradient causes protons to enter the matrix causing ATP synthase to convert ADP to ATP QUESTION 10 0.1 points Save Aswer What is substrate level phosphorylation? Using Water and CO2 to...
Describe in detail how ATPase works for ATP production and why cells may use their ATPase in reverse.
Question 36 2 pts The production of ATP by chemiosmosis is powered by o the diffusion of water molecules up a concentration gradient. the addition of electrons to ADP and phosphate o lactic acid fermentation o the proton-motive force oxaloacetate regeneration
Define "protonmotive force". Explain what enzyme complex uses this phenomenon as the driving energy for ATP synthesis in oxidative phosphorylation. Draw a diagram and provide the relevant equation. Explain the 2 contributions described by the relevant equation.
1.Describe in detail how the proton motive force (PMF) is generated and how ATP is produced from PMF.
Describe the purpose of the eTC and how it works using both NADH and FADH2 as examples, and how it maintains the proton gradient. Then explain how ATP synthase utilizes the gradient in order to make ATP, and approximately how many ATP are produced by ATP synthase per glucose molecule.
