Biology 133 Exam 2: Chapters 7-11
Exam Questions And Answers.
The reduction of NADP+ → NADPH occurs because there are - Answer electrons from water and energy
from ATP
Question 2
Normal watermelons (n=11) are diploid. - Answer How many chromosomes are in a sperm cell? 11
How many chromosomes are in a normal watermelon somatic cell? 22
Question 3
Teeth can have a biofilm formed on the surface. Cell signaling will - Answer increase cell quantity
Question 4
C6H12O6 + 6O2 → 6H2O + 6CO2 is an example of ____________. (This question refers to what is
occurring on the right side of the reaction.) - Answer oxidation
Question 5
Molecules generated from butter will enter aerobic cellular respiration at - Answer pyruvate oxidation
Question 6
Removal of NH3 is best described as ____________ . - Answer deamination
Question 7
To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll
meter" that measures the amount of green light reflected off a leaf.Why does this provide an indication
of whether the plant may need more or less nitrogen? - Answer Nitrogen gas is green, and
photosynthesis uses N2 to run the Calvin cycle.

Question 10
Almost all life cycles will have haploid and diploid phases. The transition from haploid to diploid occurs -
Answer when gametes fuse during fertilization
Question 11
Protein phosphorylating enzymes help regulated gene expression by - Answer protein activation
Question 12
Cancer is caused by unregulated cell growth. One way to attack cancer cells is to harness the power of
signaling pathways. For each type of drug, match it to the component of the pathway it would bind to.
