MCB Exam #4 Q & As (Verified Answers)
2026 Update
Genetic Material must meet criteria (4): - Correct Answers
✅-Information
-Replication
-Transmission
-Variation
List the 3 specific ways that enzymes can bring about this
change in the reaction - Correct Answers ✅-Positioning
substrates closer together to lower the activation energy
-Temporary bonding to lower the activation energy
-Changes in the local environment lowers the activation
energy
What predictions would you make about ATP production in
the cell if the second H+ pump in the ETC is inhibited? This
inhibition leaves the other components of the ETC and
chemiosmosis intact and functioning normally. - Correct
Answers ✅The ATP production would decrease because
there are fewer H+ pumped through the intermembrane
space. ATP synthase would be affected because the less
energy (ATP) and fewer H+ determines the productions
progress.
Chemiosmosis is to _________ ATP(s) as substrate-level
phosphorylation in glycolysis is to 4 ATPs - Correct Answers
✅30-34
Events of mitosis in order - Correct Answers ✅-Sister
chromosomes condense
-Sister chromatids align on the metaphase plate
-Sister chromatids separate

In which phase of mitosis would you expect to see the sister
chromatids separating (now called chromosomes)? - Correct
Answers ✅Anaphase
Select the best description of the relationship of sister
chromatids during mitosis: - Correct Answers ✅-They are
identical
-They are produced during S phase
Which of the following events typically occurs during
telophase, but is NOT part of mitosis? - Correct Answers
✅cytokinesis
Mitosis results in the formation of 2 genetically identical
daughter cells. This is because: - Correct Answers ✅All the
genetic material is duplicated then segregated equally to the
daughter cells
Which term best describes the following passage? The
nucleus of a diploid cell contains 2 sets of chromosomes. The
maternal and paternal sets of chromosomes are functionally
equivalent; each set carries the same set of genes, but may
carry different alleles. - Correct Answers ✅homologous
chromosomes
Which of the following statements is correct about the cell
cycle: - Correct Answers ✅The cell spends most of its life
in interphase, which includes processes such as growth, DNA
replication, centriole replication, and normal metabolic
functioning
