What is the final electron acceptor in photosynthesis?

NADP
The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used.

What is meant by final electron acceptor?

Final Electron Acceptor thus is the final thing (compound) to accept an electron, particularly at the point where the organism or at least biochemical pathway is now done (finished) with the electron.

What is the final electron acceptor in the electron transport system and what is formed?

At the end of the electron transport system, two protons, two electrons, and half of an oxygen molecule combine to form water. Since oxygen is the final electron acceptor, the process is called aerobic respiration.

What is the final electron acceptor in cellular respiration quizlet?

Oxygen is used in the ETC in respiration since oxygen is the final electron acceptor.

What are the final electron acceptors for the electron transport chains in the light reactions of photosynthesis and in cellular respiration?

20. What are the final electron acceptors for the electron transport chains in the light reactions of photosynthesis and in cellular respiration? c. H2O in the light reactions and O2 in respiration.

What is the final electron acceptor in photosynthesis vs cellular respiration?

Reaction kinetics

The electron acceptor in photosynthesis is NAD+ while in respiration the electron acceptor is NADH. In cellular respiration reaction 36 molecules of ATP are produced in complete oxidation of one molecule of glucose.

Which of the following final electron acceptors is used during anaerobic respiration?

Anaerobic respiration is the formation of ATP without oxygen. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor. Instead, molecules such as sulfate (SO42), nitrate (NO3), or sulfur (S) are used as electron acceptors.

What is the final electron acceptor in the process that occurs in winemaking?

The inputs of cellular respiration are sugar (and other energy-packed food molecules) and ________; the outputs are _________, water, and energy in the form of ATP. What is the final electron acceptor in the process that occurs in winemaking? … cellular respiration by yeast that occurs in the absence of oxygen.

What is the electron acceptor in alcoholic fermentation?

a. Triose phosphate is the electron donor, while acetaldehyde is the electron acceptor.

What is the final electron acceptor at the end of the electron transport chain in photosynthesis quizlet?

NADP is a coenzyme that serves as the final electron acceptor at the end of the electron transport chain in the non-cyclic light-dependent reactions of photosynthesis.

What is the final electron acceptor in the Calvin cycle?

(***NADH = nicotinamide adenine dinucleotide (chemically similar to NADPH, NADH is oxidized to facilitate ATP production, while NADPH is associated with biosynthesis). These reaction is essentially the reverse of the Calvin cycle. O2 is the final electron acceptor.

Which molecule is the final electron acceptor for electrons from photosystem I quizlet?

Explanation: The final electron acceptor is NADP+. As molecules are oxidized the potential energy us used to concentrate H+ ions in the thylakoid lumen space.

Is an electron acceptor?

An electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process. Electron acceptors are sometimes mistakenly called electron receptors.

What happens at the end of the electron transport chain?

At the end of the electron transport chain, electrons are transferred to molecular oxygen, which splits in half and takes up H +start superscript, plus, end superscript to form water. Gradient-driven synthesis of ATP.

What is the best electron acceptor?

Oxygen (O2) is the best electron acceptor and is used in many aerobic reactions (reactions with oxygen). Hydrogen gas (H2) is a good electron donor.

What is the final electron acceptor in electron transport that leads to the formation of metabolic water?

The electrons are then drawn to oxygen, which is the final electron acceptor. … Water is formed as oxygen receives the electrons from protein complex 4, and combines with protons on the inside of the cell.

What is the electron acceptor in the electron transport chain in the light reactions of photosynthesis?

Nicotinamide adenine dinucleotide phosphate, an energy carrier molecule produced in the light reactions of photosynthesis. NADPH is the reduced form of the electron acceptor NADP+. At the end of the light reactions, the energy from sunlight is transferred to NADP+, producing NADPH.

What are the final electron acceptors in the light reactions and where are the electrons utilized?

What are the final electron acceptors in light reactions, and where are the electrons utilized? NADP+ accepts the electrons to become NADPH; the electrons are used in the Calvin Cycle to form the bonds between fixed carbon molecules. … – The light reactions take place inside the thylakoids of chloroplasts.

How are the protons H +) from #7 produced where?

How are the protons (H+) from #7 produced? … In most cases the proton-motive force is generated by an electron transport chain which acts as a proton pump, using the Gibbs free energy of redox reactions to pump protons (hydrogen ions) out across the membrane, separating the charge across the membrane.

What is the final electron acceptor of aerobic respiration and what is the final electron acceptor for anaerobic respiration?

Aerobic respiration uses oxygen as a final electron acceptor, whereas anaerobic respiration uses an inorganic molecule other than oxygen as the final electron acceptor. -In anaerobic respiration, the final electron acceptor is an inorganic substance other than oxygen, such as nitrate, sulfate, or carbonate.

Where is the final electron acceptor in aerobic respiration?

In aerobic respiration, the final electron acceptor (i.e., the one having the highest or most positive redox potential) at the end of the ETS is an oxygen molecule (O2).

How is NADH recycled to NAD+?

In the process of fermentation the NADH + H+ from glycolysis will be recycled back to NAD+ so that glycolysis can continue. In the process of glycolysis, NAD+ is reduced to form NADH + H+. … During aerobic respiration, the NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis again.

Which is the end product of anaerobic respiration?

The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals.

When the final electron acceptor during the energy harvesting process is an organic molecule What is the process called?

Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. Fermentation includes processes that use an organic molecule to regenerate NAD+ from NADH.

Which molecule is the final electron acceptor in alcohol fermentation?

Pyruvate typically serves as the final electron acceptor during fermentation.

What is the electron acceptor in anaerobic respiration?
