Question 1

Which of the following best describes the process of catabolism in human metabolism?

Accepted Answer

The breakdown of complex molecules into simpler ones, releasing energy.

Accepted Answer

Oxygen, because it is essential for the chemical reactions that produce ATP.

Question 3

Which of the following is an example of positive feedback in the human body?

Accepted Answer

Childbirth, where uterine contractions intensify until delivery.

Question 4

A person suffers a deep cut on the lateral side of their right leg. Which anatomical term best describes the location of the injury?

Accepted Answer

Lateral

Question 5

Which imaging technique is best suited for observing metabolic activity and blood flow in tissues?

Accepted Answer

PET (Positron Emission Tomography)

Question 6

During homeostasis, which component is responsible for detecting changes in a physiological value?

Accepted Answer

Sensor

Question 7

Which body plane divides the body into anterior and posterior portions?

Accepted Answer

Frontal (Coronal)

Question 8

If a patient is experiencing difficulty in maintaining internal temperature, which requirement for life is most directly compromised?

Accepted Answer

Homeostasis

Question 9

Which of the following best illustrates the concept of responsiveness in living organisms?

Accepted Answer

Muscles contracting in response to a painful stimulus.

Question 10

A cross-sectional image of the brain is needed for diagnosis. Which imaging technique and body plane would be most appropriate?

Accepted Answer

CT scan and transverse plane

Question 11

Which equation correctly represents the breakdown of glucose during cellular respiration to produce ATP?

Accepted Answer

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} ightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{ATP}$$

Accepted Answer

Brain

Question 14

Which of the following best describes the role of the control center in negative feedback?

Accepted Answer

It compares the value to a normal range and initiates a response if needed.

Question 15

Which term describes a position closer to the point of attachment of a limb to the trunk?

Accepted Answer

Proximal

Question 16

Which of the following is NOT a requirement for life as described in the study materials?

Movement

Question 17

A patient is unable to respond to external stimuli. Which fundamental property of life is most directly impaired?

Accepted Answer

Responsiveness

Question 18

Which of the following best describes the transverse plane?

Accepted Answer

Divides the body into upper and lower portions.

Question 19

Which imaging technique uses magnetic fields and radio waves to produce detailed images of soft tissues?

Accepted Answer

MRI

Question 20

Which of the following is the correct sequence of components in a negative feedback loop?
