What is electron transfer chain reaction?

What is electron transfer chain reaction?

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

What is the electron transport chain easy explanation?

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are passed from one member of the transport chain to another in a series of redox reactions. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation.

How many ATP does it take to activate a fatty acid?

2 ATP

How much ATP does a 20 carbon fatty acid produce?

1,200 ATP

What is the end product of fatty acid oxidation?

The final product of β-oxidation of an even-numbered fatty acid is acetyl-CoA, the entry molecule for the citric acid cycle.

How much ATP does a 15 carbon fatty acid produce?

Therefore, total yield of ATP from the C15 fatty acid is: -2+34+15+51-1+21 = 118 ATP.

How many ATP does acetyl-CoA produce?

Every acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (=ATP) during Krebs cycle. Considering an average production of 3 ATP/NADH and 2 ATP/FADH2 using the respiratory chain, you have 131 ATP molecules.

What is acetyl CoA and why is it important?

Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.

How is acetyl CoA produced?

Acetyl-CoA is generated either by oxidative decarboxylation of pyruvate from glycolysis, which occurs in mitochondrial matrix, by oxidation of long-chain fatty acids, or by oxidative degradation of certain amino acids. Acetyl-CoA then enters in the TCA cycle where it is oxidized for energy production.
