Question

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 transfer PO4 to ADP Using other food sources (proteins and fats) to the electron transfer system to produce ATP All of these are involved in substrate level phosphorylation Transferring energy from a substrate to add a PC4 group to ADP creating ATP outside ETS)

Answer 1

1) ATP synthase rotating to add phosphate to ADP = ATP

Chemiosmosis refers to movement of ions across a membrane along their electrochemical gradient .

Example : Synthesis of ATP by ATPsynthase . Movement of H+ ions from intermembrane space of mitochondria to inner mitochondrial matrix releases energy which helps in ATP synthesis

2) Substrate level phosphorylation

Transferring energy from substrate to add a PO4- group to ADP creating ATP ( outside ETS )

Examples of substrate level phosphorylation

Phosocretinine --------> creatinine + ATP

Phosphoenolpyruvate -----------> pyruvate + ATP
