Exam 4: Physiology of Cells

The three processes that comprise cellular respiration are glycolysis,the citric acid cycle,and the proton transport system.

Match each term with its description. -process also called the Krebs cycle

Match each term with its description. -last step in cellular respiration

The location at which the enzyme molecule binds to the substance it acts on is called the:

Which of the following is not true of glycolysis?

Match each term with its description. -converted from pyruvic acid if no oxygen is present

The energy storage molecules NADH and FADH₂ have their energy converted to ATP in the electron transport system.

Which enzymes rearrange atoms within a molecule?

If a cell were placed in a hypotonic solution:

Facilitated diffusion is a metabolically inexpensive process.

If a blood cell was placed in a solution and the cell began to swell and take in water,the solution would be called hypotonic to the cell.

Match each term with its description. -carries the end product of glycolysis to the citric acid cycle

The engulfing of microbes by white blood cells is an example of:

Digestive enzymes belong to a group of enzymes called hydrases.

The small water channels in the cell membrane are called:

A hypertonic solution has a higher amount of osmotic potential than any other type of solution.

The force of a fluid pushing against a surface could be described as _____ pressure.

Match the name of each enzyme with its function or description. -involved in oxidation-reduction reactions

The measurement of potential osmotic pressure is easier to determine than actual osmotic pressure.
