What is the purpose of oxygen in aerobic respiration? A) Oxygen accepts electrons at the end of the electron transport chain B) Oxygen is necessary to carry away the waste carbon dioxide C) Oxygen is used in the formation of sugar molecules D) The oxygen molecule becomes part of the ATP molecule

Aerobic respiration produces more ATP than anaerobic respiration per molecule of glucose. 

Which of the following stages of mitosis is represented in the image below?

The following diagram shows a substrate, an enzyme, and an enzyme after the addition of heat. How will this addition of heat affect the enzyme activity for this reaction. 

  Which curves on the graphs in Figure 6.3 may represent the temperature and pH profiles of an enzyme taken from a bacterium that lives in a mildly alkaline (basic) hot spring at temperatures of 70°C or higher?  A) curves 1 and 5 B) curves 2 and 4 C) curves 2 and 5 D) curves 3 and 4 E) curves 3 and 5

Which of the following is true concerning cancer cells?  A) They exhibit density-dependent inhibition when growing in culture.  B) They must be attached to a substrate to divide in culture.  C) They evade the normal controls that trigger programmed cell death.  D) They stop dividing in culture when growth factors are depleted.

Which form of chemical reaction is responsible for converting a molecule of ADP to ATP? A) hydrolysis B) dephosphorylation C) phosphorylation D) glycolytic reaction

The following image depicts a cellular process which is essential for providing genetic diversity in sexually reproducing organisms. What cellular process is shown below? A) Anaphase B) Crossing over C) Apoptosis D) Binary Fission

The addition of heat is the best way to speed up chemical reactions in cells because it speeds up the movement of molecules in the cell. 

Using the following diagram, identify the items in this enzyme-mediated reaction.
