What are the two catabolic pathways that lead to cellular energy production?
- A. Fermentation and internal respiration
- B. Fermentation and external respiration
- C. Fermentation and cellular respiration
- D. Fermentation and anaerobic respiration
Correct Answer: C
Rationale: The correct answer is C: Fermentation and cellular respiration. Fermentation and cellular respiration are the two catabolic pathways that lead to cellular energy production. Fermentation occurs in the absence of oxygen and produces a small amount of ATP, while cellular respiration involves the breakdown of glucose in the presence of oxygen to produce a much larger amount of ATP through a series of metabolic pathways.
Which of the following epithelial types is correctly matched with its major function?
- A. Simple squamous epitheliumĀ"secretion or absorption
- B. Stratified squamous epitheliumĀ"changes shape when stretched
- C. Stratified squamous epitheliumĀ"diffusion
- D. Simple columnar epitheliumĀ"secretion or absorption
Correct Answer: D
Rationale: The correct answer is D - Simple columnar epitheliumĀ"secretion or absorption. Simple columnar epithelium is typically found in areas where secretion or absorption is the primary function, such as the lining of the intestines. This type of epithelium is composed of a single layer of tall, narrow cells that are well suited for these functions. Simple squamous epithelium is more associated with diffusion due to its thin structure allowing for easy movement of molecules through it. Stratified squamous epithelium is designed to protect underlying tissues and is not primarily involved in diffusion.
What is the function of the thrombocytes?
- A. Form connective tissue.

- D. Transport respiratory gases.
Correct Answer: B

What is the name of the process in the lungs by which oxygen is transported from the air to the blood?
- A. osmosis
- B. diffusion
- C. dissipation
- D. reverse osmosis
Correct Answer: B
Rationale: The correct answer is B, diffusion. Diffusion is the process by which oxygen moves from an area of high concentration (in the air) to an area of low concentration (in the blood) through the alveoli in the lungs. Osmosis involves the movement of water molecules across a semipermeable membrane, not oxygen molecules. Dissipation refers to the dispersal or scattering of something. Reverse osmosis is a process used in water purification, which is not relevant to the transport of oxygen in the lungs.
What substance makes up the pads that provide support between the vertebrae?
- A. bone
- B. cartilage
- C. tendon
- D. fat
Correct Answer: B
Rationale: Cartilage is the substance that makes up the pads providing support between the vertebrae. These pads, known as intervertebral discs, consist of tough outer layers of fibrous cartilage and a gel-like inner core. Cartilage plays a crucial role in cushioning the vertebrae, absorbing shock, and maintaining flexibility in the spine.
