Biology 133 Exam question with correct
answers
Question 1
The reduction of NADP+ → NADPH occurs because there are - verified answers; electrons
from water and energy from ATP
Question 2
Normal watermelons (n=11) are diploid. - verified answers; 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 - verified answers; 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.) - verified answers; oxidation
Question 5
Molecules generated from butter will enter aerobic cellular respiration at - verified answers;
pyruvate oxidation
Question 6
, Removal of NH3 is best described as ____________ . - verified answers; 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? - verified
answers; Nitrogen gas is green, and photosynthesis uses N2 to run the Calvin cycle.
Question 8
What vitamin acts as a coenzyme in cell respiration and is important in alcohol fermentation?
- verified answers; thiamine
Question 9
What area is not involved with pumping protons to the intermembrane space? - verified
answers; complex II
Question 10
Almost all life cycles will have haploid and diploid phases. The transition from haploid to
diploid occurs - verified answers; when gametes fuse during fertilization
Question 11
Protein phosphorylating enzymes help regulated gene expression by - verified answers;
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.
