What triggers the sensation to eat in order to supply our bodies with energy?
- A.
Cells in the stomach
- B.
The Hypothalamus
- C.
Blood glucose levels
Correct Answer
B. The HypothalamusExplanation
The hypothalamus is responsible for regulating hunger and satiety signals in the body. It receives information from various sources, including blood glucose levels, to determine when the body needs energy. When blood glucose levels drop, the hypothalamus sends signals to stimulate hunger and initiate the sensation to eat, ensuring that the body is supplied with the energy it needs. Therefore, the hypothalamus triggers the sensation to eat in order to supply our bodies with energy.Rate this question:

Energy expended by organs and resting muscles makes up the greatest proportion of REE
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the resting energy expenditure (REE) refers to the amount of energy the body needs to perform basic functions while at rest. Organs such as the brain, heart, liver, and kidneys require a significant amount of energy to function properly. Additionally, even when the body is at rest, muscles still need energy to maintain their tone and support posture. Therefore, the energy expended by organs and resting muscles does indeed make up the greatest proportion of REE.Rate this question:

Age, height and physical activity impact your BMR
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Age, height, and physical activity do not directly impact your Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to perform basic functions at rest. While age and height can indirectly affect BMR by influencing factors such as muscle mass and body composition, they do not directly impact BMR. Physical activity, on the other hand, affects Total Daily Energy Expenditure (TDEE), which includes BMR plus calories burned through physical activity. So, the statement that age, height, and physical activity impact BMR is false.Rate this question:

The structural parts of plants would include which of the following:
- A.
Cellulose
- B.
Hemicellulose
- C.
Pectin
- D.
All of the above
- E.
A and B only
Correct Answer
E. A and B onlyExplanation
The correct answer is "A and B only" because cellulose and hemicellulose are both structural components of plants. Cellulose forms the main structural component of plant cell walls, providing strength and rigidity. Hemicellulose, on the other hand, is a complex carbohydrate that helps to bind cellulose fibers together, contributing to the overall structural integrity of plants. Pectin, although a component of plant cell walls, is not considered a structural component in the same way as cellulose and hemicellulose.Rate this question:

Glucose is the preferred fuel for the brain, red blood cells, liver and nervous system
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false. While glucose is indeed an important fuel for the brain, red blood cells, liver, and nervous system, it is not the only preferred fuel. The brain, for example, can also use ketones as an alternative fuel source during periods of fasting or low carbohydrate intake. Additionally, the liver can metabolize other substances, such as fatty acids, to produce energy. Therefore, while glucose is important, it is not the exclusive preferred fuel for these systems.Rate this question:

Humans store glucose in the form of glycogen
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Glucose is stored in the human body in the form of glycogen. When we consume carbohydrates, they are broken down into glucose, which is then converted into glycogen and stored in the liver and muscles. This stored glycogen can later be broken down into glucose to provide energy when needed, such as during periods of fasting or intense physical activity. Therefore, the statement that humans store glucose in the form of glycogen is true.Rate this question:

Liver glycogen stores account for two-thirds of the body's total glycogen stores
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Liver glycogen stores do not account for two-thirds of the body's total glycogen stores. While the liver does store a significant amount of glycogen, it is not the majority. Muscle tissue actually holds the largest amount of glycogen in the body, accounting for around two-thirds of the total glycogen stores. Therefore, the statement is false.Rate this question:

Where is pepsin, the protein-digesting enzyme, produced?
- A.
Liver
- B.
Stomach
- C.
Pancreas
- D.
Small Intestine
Correct Answer
B. StomachExplanation
Pepsin, the protein-digesting enzyme, is produced in the stomach. The stomach contains specialized cells called chief cells that produce pepsinogen, an inactive form of pepsin. When pepsinogen comes into contact with the acidic environment of the stomach, it is converted into its active form, pepsin. Pepsin then helps break down proteins into smaller peptides, aiding in the digestion process.Rate this question:
