Question 5
What role does oxygen play in the electron transport chain (ETC)?
Correct
5.00 points out Select one:
of 5.00 a. Oxygen helps to transfer the electrons from complex I to complex IV which helps in ATP
production.
b. Oxygen is an important component in ETC and serves as a reactant in the production of ATP.
c. Oxygen is the final electron acceptor, allowing the continuation of electron flow through
the chain.
d. Oxygen is an important component in ETC and is produced as a byproduct of ATP synthesis.
Question 6
Which of the following statements regarding the postabsorptive state is INCORRECT?
Correct
5.00 points out Select one:
of 5.00 a. Gluconeogenesis occurs in the liver to replace glucose used by peripheral tissues.
b. The liver absorbs and processes excess glucose during prolonged fasting.
c. Glucose levels in the blood drop as it is absorbed and used by the cells.
d. Glucagon inhibits the synthesis of glycogen in the liver.
Question 7
Consider a scenario where an individual has voluntarily fasted for 48 hours as part of a scientific
Correct
experiment. As the fasting period progresses, what metabolic adjustments occur as the body
5.00 points out transitions from the fasting state to the postabsorptive state?
of 5.00
Select one:
a. Glucagon secretion decreases, resulting in an increased rate of gluconeogenesis in the liver.
b. Adipose tissue releases stored triglycerides into the bloodstream for energy production.
c. Muscle cells increase glycogen synthesis to prepare for immediate energy demands.
d. Insulin levels dramatically decrease, prompting the liver to release stored glycogen into the
bloodstream.
Question 8
During a health assessment, a physician is evaluating a patient's metabolic rate. The patient, a
Correct
middle-aged individual, leads a sedentary lifestyle and has noticed gradual weight gain over the
5.00 points out past few years despite not significantly changing their diet. The physician explains that the patient's
of 5.00 basal metabolic rate (BMR) plays a crucial role in their energy expenditure. Which of the following
statements accurately reflects the impact of BMR on the patient's weight gain?
Select one:
a. Because the patient is middle-aged, their BMR is likely to increase, resulting in a higher
metabolic rate and weight loss.
b. An increase in body temperature regulation, which requires 10 percent of the daily energy
expenditure, is the main reason for the patient's weight gain.
c. The patient's weight gain is primarily due to excessive physical activity, which has increased
their BMR, leading to higher energy expenditure.
d. The patient's sedentary lifestyle and decreasing muscle mass contribute to a lower BMR,
resulting in reduced energy expenditure and gradual weight gain.
