Answer:

E1: Pyruvate dehydrogenase, TPP, oxidative decarboxylation reaction

E2: Dihydrolipoyl transacetylase, Lipoamide and Co-enzyme A, transacetylation reaction.

E3: Dihydrolipoyl dehydrogenase, FAD and NAD+, oxidation reaction

Explanation:

Pyruvate dehydrogenase is a multi-enzyme complex with 5 co-enzymes and 3 apo-enzymes:

Pyruvate dehydrogenase (E1) , which uses thiamine pyrophosphate (TPP) as as co-enzymes to catalyze oxidative decarboxylation of pyruvate to hydroxyethyl-TPP.

Dihydrolipoyl transacetylase (E2): which uses lipoamide and coenzyme A as co-enzymes to catalyse the transacetylation from TPP to Lipoamide to form acetyl lipoamide.

Dihydrolipoyl dehydrogenase (E3)​​ which uses FAD and NAD+ as co-enzymes to catalyze the oxidation of lipoamide

marin [14]
This could be a mutualism rather than a commensal relationship because when<span> "cleaner fish" consume parasites and mucus from the skin of larger fish, they don't only receive food from the relationship, eliminating parasite and such from the large fish, but also they gain protection from predators, thus making the relationship a good example of mutualism, because both parts of the relationship gain something from the relationship itself. </span>

Surface area is an important factor in limiting cell growth because
julia-pushkina [17]

Surface area is an important factor in limiting cell growth because

a. the cell can burst if the membrane becomes too large.

b. materials cannot enter the cell if the surface is too large.

c. the cell may become too large to take in enough food and to remove enough wastes.

d. waste products cannot leave the cell if the cell is too small.

Answer:

c. the cell may become too large to take in enough food and to remove enough wastes.

Explanation:

The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
