Does Substrate-level phosphorylation occur in the electron transport chain?

Question

Or does it only occur in glycolysis and krebs cycle?

Answer 1

no. substrate level phosphorylation occurs in glycolysis and kreb's cycle, but not electron transport chain. The reaction between proteins as they transport the electron does not release sufficient free energy to cause the phosphorylation of ADP to ATP. Conversely, in some of the steps of glycolysis and krebs cycle, sufficient free energy is released by the one step reaction to directly phorphorylate
ADP to ATP.

Answer 2

Nope, not in the ETC. You are correct that substrate level phosphorylation occurs in both glycolysis (at 2 steps) and in the TCA. I belive there is also an instance in the muscles (or maybe it is teh brain?).

Answer 3

we've a huge volume of H+ ions in the mitochondrial matrix so we positioned it into water so as that it will added enhance the proton gradient. If we initiate removing H+ ions from the mitochondrial matrix and and the H+ ions develop into some thing else or bypass for the time of the cytochromes, then we would have an more suitable proton gradient. that's called oxidative phosphorylation because of the fact oxygen is the final electron acceptor. and so on is in the past ox.phos yet technically, they are an identical technique. Like Telophase and cytokinesis, they are on the different assistance of eachother.

Answer 4

YES!! Substrate level phosphorelyation occurs in the ECT after chemiosomsis... in glycolysis and kerbs cycle it is oxdative phosphorylation--because NAD+ is converted to NADH or FAD is converted to FADH2

Answer 5

In cells, it occurs in the cytoplasm (in glycolysis) and the mitochondrial matrix or cytoplasm (in the citric acid cycle) under both aerobic and anaerobic conditions.

Substrate-level phosphorylation is also seen in working skeletal muscles and the brain.
