What else can I help you with?
Is ATP considered an electron carrier?
No, ATP is not considered an electron carrier. ATP is the primary energy-carrying molecule in cells, storing and transferring energy for cellular processes. Electron carriers like NADH and FADH2 are involved in the transport of electrons during cellular respiration.
Nadh delivers electrons to an electron what?
NADH delivers electrons to the electron transport chain in the mitochondria during cellular respiration. This transfer of electrons helps to generate a proton gradient across the inner mitochondrial membrane, which drives the production of ATP through oxidative phosphorylation.
How does NADP transfer electrons?
NADP transfers electrons by accepting them from other molecules in redox reactions, taking on two electrons and a proton to form NADPH. This process typically occurs in metabolic pathways such as photosynthesis and cellular respiration, where NADP acts as an electron carrier to facilitate energy production.
During what does most energy release in the mitochondria?
The majority of energy within the mitochondria is released during the process of cellular respiration, specifically during the electron transport chain and oxidative phosphorylation. This is where the majority of ATP, the cell's primary energy source, is produced.
Why do high-energy electrons need carrier molecules?
High-energy electrons are unstable and reactive, so they need carrier molecules to transport them safely without causing damage to the cell. Carrier molecules such as NADH and FADH2 can carry high-energy electrons during cellular respiration, allowing them to participate in energy-producing reactions without causing harm.
Does cellular respiration use NADPH as its electron carrier?
No. Cellular respiration uses NADH as an electron carrier. NADPH is used in photosynthesis.
What is electron carrier use to transfer energy in cellular respiration?
NADH.
An electron carrier used to transfer energy in cellular respiration?
Nicotinamide adenine dinucleotide or NAD+.
Which electron carrier is used in the redox reactions in a cellular respiration?
NAD plus
What acts like an electron carrier in cellular respiration?
ADP/ATP (adenine-tri- phosphate)
NAD plus is a carrier for what?
NAD+ is an electron carrier used in cellular respiration. With the addition of an electron and a hydrogen, it becomes NADH. NADH is formed in glycolysis and the Krebs Cycle and is used for the formation of ATP in the Electron Transport Chain, providing energy for the cell.
Is ATP considered an electron carrier?
No, ATP is not considered an electron carrier. ATP is the primary energy-carrying molecule in cells, storing and transferring energy for cellular processes. Electron carriers like NADH and FADH2 are involved in the transport of electrons during cellular respiration.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Where does the first electron carrier pump hydrogen ions?
The first electron carrier that pumps hydrogen ions during cellular respiration is NADH dehydrogenase (complex I) in the electron transport chain. It pumps hydrogen ions across the inner mitochondrial membrane from the matrix to the intermembrane space.
What are organisms called that use organic compounds as electron donors in cellular respiration?
Lithotrophs are organisms that use inorganic compounds as electron donors in cellular respiration.
What acts as an electron carrier in cellular respiration?
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) are electron carriers in cellular respiration. They accept electrons and hydrogen ions from molecules during the process of converting food into energy.
What is the electron acceptor in aerobic cellular respiration?
oxygen
