Answer:
B. glucose – NADH – electron transport – O2
Explanation:
This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.
During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .
The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .
The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.
The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.
The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.
The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
The two types are abiotic and biotic
Thé things that make up the community is fox , snakes, rocks, trees ect.
For photosynthesis you will need co2 water and sunlight to produce oxygen and glucose
Synergistic Interaction
Hope helps uh :)
