Question

Which statement most accurately describes the differences between respiration and fermentation? Fermentation uses a single substrate as an electron donor and acceptor while respiration uses different substrates. There is no difference between fermentation and respiration. Fermentation uses oxidative phosphorylation for ATP synthesis, respiration uses substrate-level phosphorylation. Respiration uses NADH as an electron carrier, fermentation does not. Respiration uses a single substrate as an electron donor and acceptor while fermentation uses different substrates.

Answer 1

Answer:

Respiration uses NADH as an electron carrier, fermentation does not

Explanation:

Respiration is the process of chemical reactions, in oxidising food to generate energy.

Fermentation is chemical breakdown of organic substrate, like glucose, by microrganisms like bacteria & yeast.

Difference between them is that : Respiration process uses NADH in oxidative phosphoralytion for ATPs . However, fermentation doesn't include use of  NADH in oxidative phosphoralytion for ATPs.
