Living things are made up of different systems that help to sustain their life. Under physiology, there are a lot of secrets we can uncover about living things, and it is very helpful when it comes to the medical field. The quiz below is designed to help you envision just how much you have come to understand so far. Give it a shot and get to refresh your memory.

Questions and Answers

1.

For a basketball player who likes to slam dunk, what type of anaerobic training would be the most appropriate:
- A.
  
  Wingate
- B.
  
  Sprint
- C.
  
  Vertical Jump
- D.
  
  None of the above
Correct Answer
C. Vertical Jump

Explanation
The most appropriate type of anaerobic training for a basketball player who likes to slam dunk would be vertical jump training. Vertical jump training focuses on increasing the power and explosiveness of the leg muscles, which is essential for achieving a higher vertical jump. This type of training typically involves exercises such as plyometrics, squats, and jump training drills, all of which help to improve the athlete's ability to generate force and propel themselves upwards for a successful slam dunk.

The short term energy system largely depends on:
- A.
  
  Lipids
- B.
  
  Protein
- C.
  
  Glycogen
- D.
  
  Lactate
Correct Answer
C. Glycogen

Explanation
The short term energy system largely depends on glycogen. Glycogen is a form of stored glucose in the body, primarily found in the liver and muscles. When the body needs quick energy, glycogen is broken down into glucose, which can be used by the cells to produce ATP, the body's main source of energy. This process is especially important during high-intensity activities or short bursts of exercise, where the body requires immediate energy. Lipids and proteins are not typically used as immediate energy sources, and lactate is a byproduct of anaerobic metabolism, not a primary energy source.

The contribution of anaerobic and aerobic energy transfer depends on:
- A.
  
  Type of exercise and rest
- B.
  
  Exercise intensity and recovery
- C.
  
  Exercise intensity and duration
- D.
  
  None of the above
Correct Answer
C. Exercise intensity and duration

Explanation
The contribution of anaerobic and aerobic energy transfer depends on exercise intensity and duration. This means that the amount of anaerobic and aerobic energy used during exercise is determined by how intense the exercise is and how long it lasts. Higher intensity exercises tend to rely more on anaerobic energy transfer, while lower intensity exercises rely more on aerobic energy transfer. Similarly, longer duration exercises require a greater contribution from aerobic energy transfer, while shorter duration exercises may rely more on anaerobic energy transfer.

4.

Which method is used to safely estimate total and average daily energy expenditure without constraints imposed by laboratory procedures.
- A.
  
  Bomb calorimeter
- B.
  
  Human calorimeter
- C.
  
  Doubly labeled water
- D.
  
  Boiling point
Correct Answer
C. Doubly labeled water

Explanation
Doubly labeled water is used to safely estimate total and average daily energy expenditure without constraints imposed by laboratory procedures. This method involves the administration of water labeled with isotopes of hydrogen and oxygen, which allows for the measurement of carbon dioxide production and thus the calculation of energy expenditure. Unlike other methods listed, such as bomb calorimeter and human calorimeter, doubly labeled water does not require subjects to be confined to a laboratory setting, making it a more practical and accurate approach for estimating energy expenditure in real-life conditions.

5.

Which of the following is the most rapidly available source of energy within a muscle cell?
- A.
  
  Phosphocreatine
- B.
  
  Adenylate Kinase
- C.
  
  Glycogen
- D.
  
  Creatine Kinase
Correct Answer
A. Phosphocreatine

Explanation
Phosphocreatine is the most rapidly available source of energy within a muscle cell. When ATP is broken down during muscle contraction, phosphocreatine donates a phosphate group to ADP, regenerating ATP quickly. This process does not require oxygen and can provide immediate energy for short bursts of intense activity. Adenylate Kinase, Creatine Kinase, and Glycogen are also involved in energy production within muscle cells, but they are not as rapidly available as phosphocreatine.

Rate this question:
6.

Which of the following catabolic processes only occurs in the presence of oxygen?
- A.
  
  Phosphocreatine hydrolysis
- B.
  
  Glycolysis
- C.
  
  Hydrolysis of ATP
- D.
  
  Fatty acid catabolism
Correct Answer
D. Fatty acid catabolism

Explanation
Fatty acid catabolism is the correct answer because it refers to the breakdown of fatty acids to produce energy, and this process only occurs in the presence of oxygen. Oxygen is required for the complete oxidation of fatty acids in the mitochondria, which generates a large amount of ATP. In contrast, phosphocreatine hydrolysis, glycolysis, and hydrolysis of ATP can occur in the absence of oxygen, although their efficiency and ATP production may be lower in anaerobic conditions.

7.

What is the role of lipase in fat metabolism?
- A.
  
  Catalyst for the reaction that splits triacylglycerol into glycerol and fatty acids
- B.
  
  Catalyst for the reaction that breaks down fatty acids into acetyl-CoA
- C.
  
  Assists with transport of fatty acids into the mitochondrion
- D.
  
  Assists with transport of fatty acids in the blood
Correct Answer
A. Catalyst for the reaction that splits triacylglycerol into glycerol and fatty acids

Explanation
Lipase plays a crucial role in fat metabolism by acting as a catalyst for the reaction that breaks down triacylglycerol into glycerol and fatty acids. This enzymatic reaction is essential for the digestion and absorption of dietary fats in the body. Lipase helps to break down the complex structure of triacylglycerol, enabling the release of glycerol and fatty acids, which can then be further utilized for energy production or stored as adipose tissue.

8.

When comparing glucose and fat metabolism, which of the following is TRUE?
- A.
  
  Both can only occur in the presence of oxygen
- B.
  
  Only glucose metabolism requires the electron transport chain
- C.
  
  Glucose metabolism is slower than fat metabolism
- D.
  
  1 triacylglycerol molecule generates approximately 12 times more ATP than 1 molecule of glucose
Correct Answer
D. 1 triacylglycerol molecule generates approximately 12 times more ATP than 1 molecule of glucose

Explanation
The answer is true because during fat metabolism, the breakdown of a single triacylglycerol molecule produces more acetyl-CoA molecules, which enter the citric acid cycle and generate more ATP through oxidative phosphorylation. In contrast, glucose metabolism produces fewer acetyl-CoA molecules per molecule of glucose, resulting in less ATP production. Therefore, one triacylglycerol molecule generates approximately 12 times more ATP than one molecule of glucose.
