Exam 5: Microbial Metabolism

The production of NADH takes place during the _ _ stage(s) of glycolysis.

Sulfanilamide is an antimicrobial drug that mimics the shape of an important substrate for a particular bacterial enzyme, thereby inhibiting the enzyme. This type of inhibition is known as

Which of the following can be the final electron acceptor in anaerobic respiration in bacteria?

The purpose of electron transport is to create a proton (concentration/gradient/pump) across a membrane that can then be used to make ATP.

Substrate- level phosphorylation occurs during the stage(s) of glycolysis.

During chemiosmosis, electrons are pumped across a membrane to produce ATP.

If a cell reverses the process of beta- oxidation, which of the following molecules will it make?

The (transferases/transaminases/deaminases) generate amino acids from carbohydrate precursors and glutamic acid.

Enzymes known as lyases participate in reactions.

The (activation /inhibition/saturation) point of an enzyme is reached when all active sites have bound substrate molecules.

Only Photosystem I is required for (cyclic/noncyclic) photophosphorylation to occur.

Ribozymes are enzymes that cleave the subunits of the ribosome.

Some photosynthetic bacteria use chlorophylls other than chlorophyll a.

As the concentration of substrate increases, the activity of the enzyme decreases.

Where is the majority of ATP generated in most eukaryotic cells?

What is the major product of the Calvin- Benson cycle that can then be used to form glucose?

Pyruvic acid is a product of
