What is the role of NADH and FADH2 in oxidative phosphorylation?
What is the role of NADH and FADH2 in oxidative phosphorylation?
NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively. Eventually, the electrons are passed to oxygen, which combines with protons to form water.
What role do NADH and FADH2 serve in catabolism quizlet?
What role do NADH and FADH2 serve in catabolism? pyruvate releases carbon dioxide to form acetaldehyde and electrons from NADH are transferred to acetaldehyde to produce ethanol and NAD+. FADH2 electrons enter the electron transport chain at a lower energy level.
What is the function of NADH and FADH2 quizlet?
The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles. FADH2 is only produced in Krebs cycle.
Why does FADH2 yield less ATP than NADH?
FADH2 makes less ATP because it enters the electron transport chain at a later stage than does NADH. The electron transport chain is made of carrier molecules assembled into 3 protein complexes, and the passage of an electron through each complex generates enough energy to make roughly 1 ATP per complex….
What is the difference in ATP production between NADH and FADH2?
The main difference between NADH and FADH2 is that every NADH molecule produces 3 ATP molecules during oxidative phosphorylation whereas every FADH2 molecule produces 2 ATP molecules….
What process is used to make ATP in glycolysis?
Substrate -level phosphorylation
What is the function of ATP in living things?
Adenosine 5′-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.
Which process is more efficient at producing ATP?
lecture15. Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
Which type of respiration is more efficient and why?
Answer. Aerobic respiration is more effective because aerobic respiration uses oxygen to break down glucose, amino acids and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles….
Which respiration is more efficient in human?
Aerobic respiration
What are the 2 types of respiration that a cell can use to make ATP?
Summary. The cells of most living things produce ATP from glucose by aerobic cellular respiration, which uses oxygen. Some organisms can also or instead produce ATP from glucose by anaerobic respiration, which does not require oxygen….
