Exam 5: Microbial Metabolism

Explain why the ATP yield from processes such as cellular respiration is generally given as a theoretical number.

photosynthetic bacteria produce waste products such as sulfur as they obtain electrons for noncyclic photophosphorylation.

The process of using light energy to attach inorganic phosphate to ADP molecules is called .

Compare and contrast cyclic and noncyclic photophosphorylation.

All of the following are aspects of a cell's ability to regulate its metabolism EXCEPT:

Carbon dioxide is a by- product of which of the following?

Ammonia is a by- product of the catabolism of which of the following?

The is a pathway in which the energy in acetyl- CoA molecules is converted to the form of NADH and FADH2.

Types of chlorophyll differ in

All of the following are characteristics of catabolic pathways EXCEPT:

Increasing substrate concentration will increase the activity of an enzyme, up to a point.

The excited electrons that begin the light- dependent reactions of photosynthesis come from a special molecule called the chlorophyll.

When a cell forms an amino acid by adding an amine group derived from ammonia to a precursor metabolite, this process is called

A(n) is a collection of pigments such as chlorophyll that are used to absorb light in the light- dependent reactions of photosynthesis.

All of the following are true statements concerning cellular metabolism EXCEPT:

Membranes containing the photosystems necessary for photosynthesis are called

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

Another term for an organic catalyst is a(n) .

Anaerobic respiration involves the use of molecules other than as the final electron acceptor in an electron transport chain.

The denaturation of an enzyme is always irreversible.
