What are two high energy electron carriers used in cellular respiration that are not used in photosynthesis?
Two high energy electron carriers used in cellular respiration that are not used in photosynthesis are NADH (Nicotinamide Adenine Dinucleotide) and FADH2 (Flavin Adenine Dinucleotide). These molecules play a crucial role in transferring electrons from the breakdown of glucose to the electron transport chain in cellular respiration, ultimately leading to the production of ATP. In photosynthesis, the electron carriers NADH and FADH2 are not involved as the process uses different electron carriers such as NADPH (Nicotinamide Adenine Dinucleotide Phosphate) and ATP.
What else can I help you with?
What molecules serve as intermediate electron carriers in the process of cellular respiration?
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) serve as intermediate electron carriers in cellular respiration. They accept electrons from the breakdown of glucose and transfer them to the electron transport chain for the production of ATP.
Identify the electron carriers of cellular respiration?
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate, and then release waste products. The two types of electron carriers used in cellular respiration are FADH2 and NADH.
Electrons are brought to the electron transport by what high energy electron carriers?
Electrons are brought to the electron transport chain by high-energy electron carriers such as NADH and FADH2. These carriers donate electrons to the chain, which is then used to generate ATP through oxidative phosphorylation.
Why does cellular respiration produce electron carriers instead of ATP?
Cellular respiration produces electron carriers like NADH and FADH2 because they can carry high-energy electrons to the electron transport chain, where they are used to generate ATP. These electron carriers help to establish an electrochemical gradient that drives ATP synthesis through oxidative phosphorylation. This process is more efficient at producing ATP compared to direct production of ATP during earlier stages of cellular respiration.
What is the purpose of electron carriers in cellular respiration?
The purpose of electron carriers such as NADH and FADH2 is to dump electrons at the electron transport chain. This creates a proton gradient and allows oxidative phosphorylation to take place.
Does cellular respiration use NADPH as its electron carrier?
No. Cellular respiration uses NADH as an electron carrier. NADPH is used in photosynthesis.
The products of photosynthesis that begin cellular respiration are?
The products of photosynthesis that begin cellular respiration are glucose and oxygen. Glucose is broken down in the process of cellular respiration to release energy, and oxygen is used as the final electron acceptor in the electron transport chain to produce ATP.
What molecules serve as intermediate electron carriers in the process of cellular respiration?
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) serve as intermediate electron carriers in cellular respiration. They accept electrons from the breakdown of glucose and transfer them to the electron transport chain for the production of ATP.
What are the final electron acceptors for the electron transport chains in light reactions of photosynthesis and in cellular respiration?
In the light reactions of photosynthesis, the final electron acceptor is NADP+, which gets reduced to NADPH. In cellular respiration, the final electron acceptor is oxygen, which gets reduced to form water.

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 role do high energy electron carriers play in cellular respiration?
High energy electron carriers, such as NADH and FADH2, play a crucial role in cellular respiration by transferring electrons to the electron transport chain. This process generates ATP, the cell's main energy source, through a series of redox reactions.
What is the mechanism of photosynthesis in plants most similar to?
The mechanism of photosynthesis in plants is most similar to the process of cellular respiration in terms of energy transformation. Both processes involve electron transport chains and the generation of ATP, but while photosynthesis converts light energy into chemical energy stored in glucose, cellular respiration breaks down glucose to release energy. Additionally, both processes utilize similar electron carriers, such as NADP+ in photosynthesis and NAD+ in respiration. Ultimately, they are interconnected, as the products of one process serve as the reactants for the other.
What is an important similarity between photosynthesis and cellular respiration is that both processes is?
An important similarity between photosynthesis and cellular respiration is that both processes involve the transformation of energy. Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration breaks down glucose to release stored energy for cellular activities. Additionally, both processes involve a series of complex biochemical reactions and utilize electron transport chains to produce energy carriers, highlighting their interconnected roles in the ecosystem.
