QUESTIONS COMPLETE WITH 100% VERIFIED
ANSWERS
Question 1
When the chromosomes line up in mitosis this is known as which phase?
A. Telophase
B. Anaphase
C. Metaphase
D. Prophase
Correct Answer: C – Metaphase
Rationale: During metaphase of mitosis, chromosomes align along the metaphase
plate (equator) of the cell. Telophase is when chromosomes arrive at opposite
poles. Anaphase is when sister chromatids separate. Prophase is when
chromosomes condense. Therefore, alignment occurs in metaphase.
Question 2
Which cellular organelle contains enzymes that are considered digestive?
A. Golgi Apparatus
B. Lysosomes
,C. Nucleus
D. Ribosomes
Correct Answer: B – Lysosomes
Rationale: Lysosomes contain hydrolytic enzymes that break down waste, foreign
materials, and damaged organelles. The Golgi apparatus modifies and packages
proteins. The nucleus houses DNA. Ribosomes synthesize proteins. Only
lysosomes are known as the digestive organelles.
Question 3
Organs repair themselves through a process of?
A. Meiosis
B. Mitosis
C. Cellular differentiation
D. Transformation
Correct Answer: B – Mitosis
Rationale: Mitosis produces identical daughter cells for growth and repair. Meiosis
produces gametes. Cellular differentiation is when cells become specialized.
Transformation refers to genetic changes. Tissue repair requires mitotic cell
division.
Question 4
Which of the following is considered a model for enzyme action?
A. Lock and Key model
B. Enzyme interaction model
C. Transformation model
D. Transcription model
Correct Answer: A – Lock and Key model
,Rationale: The lock-and-key model describes how enzymes (lock) bind specifically
to substrates (key). The other options are not standard models for enzyme action.
Induced fit is another model, but lock-and-key is the classic answer.
Question 5
Which of the following statements about enzymes is not true?
A. Enzymes are catalysts.
B. Almost all enzymes are proteins.
C. Enzymes operate most efficiently at optimum pH.
D. Enzymes are destroyed during chemical reactions.
Correct Answer: D – Enzymes are destroyed during chemical reactions.
Rationale: Enzymes are not destroyed or consumed in reactions; they are
recycled. They are catalysts (A), mostly proteins (B), and have optimal pH (C).
Statement D is false, making it the correct choice.
Question 6
Which of the following statements about prostaglandins is not true?
A. Prostaglandins promote inflammation.
B. Prostaglandins can only constrict blood vessels.
C. Prostaglandins are made in the renal medulla.
D. Prostaglandins can lead to pain and fever.
Correct Answer: B – Prostaglandins can only constrict blood vessels.
Rationale: Prostaglandins can cause both vasodilation and vasoconstriction
depending on the type and location. They do promote inflammation (A), are
produced in the renal medulla (C), and can cause pain and fever (D). Statement B
is false because they do not only constrict.
, Question 7
Cholesterol that is known as (LDL) stands for:
A. Low-density lipoproteins
B. Low-density lysosomes
C. Level-density lipoproteins
D. Level-density lysosomes
Correct Answer: A – Low-density lipoproteins
Rationale: LDL stands for low-density lipoproteins, often called "bad cholesterol."
The other options incorrectly use lysosomes or "level-density."
Question 8
Hardening of the arteries is known as:
A. Atheriosclerosis
B. Venous narrowing
C. Micro-circulation
D. Hypertension
Correct Answer: A – Atheriosclerosis
Rationale: Atherosclerosis (often spelled arteriosclerosis for general hardening)
refers to hardening and narrowing of arteries. Venous narrowing affects veins,
micro-circulation refers to small vessels, and hypertension is high blood pressure.
Question 9
The top number on a blood pressure reading indicates:
A. Diastolic pressure
B. Transient pressure
C. Optimum pressure
D. Systolic pressure
Correct Answer: D – Systolic pressure
