Midterm II MC

Which event occurs in the fluid portion of the cytoplasm of a cell undergoing glucose metabolism?
During glycolysis, what is the net gain of ATP molecules produced from one glucose molecule?
an agent that closely mimics the structure of glucose but is not capable of being metabolized
Which kind of metabolic poison would interfere with glycolysis?
fructose bisphosphate
During glycolysis, two ATP molecules are "spent" in order to convert glucose to the highly reactive molecule:
increase the rate of glycolysis-based reactions
For bacteria to continue growing rapidly when they shift from an aerobic environment to an anaerobic environment, they must:
ATP, NADH, and pyruvate
The products of glycolysis are:
During which step of aerobic respiration is oxygen used?
are producing more C02
We breathe more heavily during exercise because our cells:
In order to be able to continue, each turn of the Krebs cycle must regenerate:
Which of the following is an example of an electron-carrier molecule?
matrix and inner membrane
Which parts of the mitochondria are directly involved in the synthesis of ATP during chemiosmosis?
is genetically identical to all others
Each of your body cells:
A bacteria cell splits into two new cells by a process called:
cell growth
What is the longest-lasting phase of the prokaryotic cell cycle?
asexual reproduction
In prokaryotes, the term "binary fission" specifically refers to:
X and Y chromosomes
The sex-determining chromosome of a human male is the:
a diploid cell
Which type of eukaryotic cell contains two types of each chromosome?
the G1 phase of interphase
During which phase of the eukaryotic cell cycle do growth and nutrient acquisition occur?
Which of the following is the correct sequence of stages in mitotic cell division?
When the two gametes that fuse to form a zygote contain different alleles of a given gene, the offspring is:
75% yellow:25% green
If we cross two pea plants, each heterozygous for yellow seed colour genes, the expected ratio of yellow:green among the offspring will be:
What type of allele produces it effects in only homozygous individuals?
Round pea shape is dominant over wrinkled pea shape. If a round pea has a wrinkled parent, the round pea is:
members of a pair of alleles move away from each other during gamete formation
Mendel's law of segregation states that:
all the offspring had purple flowers
When Mendel used true-breeding white flowers and true-breeding purple flowers as the parental generation, what were the results?
The genetic makeup of an individual is the:
an allele is dominant or recessive
A Mendelian test cross is used to determine whether:
true-breeding green-seeded plants
Yellow-seeded pea plants may be homozygous or heterozygous. To find out which, we can cross plants with:
recessive only
Crossing spherical-seeded pea plants with dented-seeded pea plants resulted in progeny that all had spherical seeds. This indicates that the dented seed trait is:
In garden peas, the allele for tall plants is dominant over the allele for short plants. Imagine that a true-breeding tall plant is crossed with a short plant. Then one of their offspring is test crossed. Out of 20 offspring resulting from the test cross, about how many should be tall?
In crossing a homozygous recessive with a heterozygote, what is the chance of getting a homozygous recessive phenotype in the F1 generation?
The sequence of subunits in the DNA "backbone" is:

"Chargaff's rule" for base pairing in DNA is that:
hydrogen bonds
Complementary base pairs are held together by:
