Nad plus picks up electrons and hydrogen forming?
NAD+ picks up two electrons and one hydrogen atom, forming NADH. This reduction reaction allows for the transfer of energy in biochemical processes such as cellular respiration.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
What is the difference between NAD and NADH?
NAD (nicotinamide adenine dinucleotide) is a coenzyme that can accept or donate electrons during cellular respiration. NADH is the reduced form of NAD, meaning it has gained electrons. NADH is a high-energy molecule that carries electrons to the electron transport chain for ATP production.
What does NADH carry that can be used in the process of chemiosmosis?
NADH carries high-energy electrons that can be used in the process of chemiosmosis to create a proton gradient across the inner mitochondrial membrane. This proton gradient is then used to generate ATP through ATP synthase.
What compound is NADH converted to when it transfers high energy electrons to the first electron carrier?
NADH is converted to NAD+ when it transfers high-energy electrons to the first electron carrier of the electron transport chain.
What happens to the high-energy electrons held by NADH if there is no oxygen present?
What happens to the high-energy electrons held by NADH if there is no oxygen present?

When NAD reacts with hydrogen and gains two electrons NAD?
is reduced to NADH. This reaction is an important step in the process of cellular respiration, where NADH then carries the electrons to the electron transport chain to produce ATP energy.
When NADH loses a hydrogen ion?
It becomes NAD. This happens during electron transport where NADH drops off its H+ and electrons to be used in oxidative phosphorylation. NAD now must move to glycolysis or citric acid cycle to regain its hydrogen.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.

What happens when NAD plus becomes NADH?
When NAD+ is reduced to NADH, it accepts two electrons and a hydrogen ion, becoming a carrier of high-energy electrons. This conversion usually occurs during cellular respiration where NADH is a key player in transferring electrons to the electron transport chain for ATP production.
What is the carrier for energy and high energy electrons during glycolysis?
nadh!
What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
Is nadh oxidized or reduced compared to nad plus?
NADH is reduced compared to NAD+ because it gains electrons and a hydrogen ion to form NADH during cellular respiration. In this process, NAD+ acts as an electron carrier that accepts electrons and a hydrogen ion from substrates being oxidized, converting it to NADH.
What does NADH carry that can be used in the process of chemiosmosis?
NADH carries high-energy electrons that can be used in the process of chemiosmosis to create a proton gradient across the inner mitochondrial membrane. This proton gradient is then used to generate ATP through ATP synthase.
What would happens to high energy electrons and hydrogen held by NADH if there is no O2 present?
Without oxygen present, high-energy electrons from NADH cannot be passed down the electron transport chain for ATP production through oxidative phosphorylation. This can lead to a buildup of NADH and a decrease in the availability of NAD+ for glycolysis and the Krebs cycle. As a result, the cell may shift to less efficient processes like fermentation to regenerate NAD+ and keep glycolysis running.
