TEAS Test 7 science quizlet

1. Which organelle is responsible for cellular respiration, producing ATP for energy?

Correct answer: B

Rationale: The correct answer is B) Mitochondria. Mitochondria are known as the powerhouse of the cell because they are responsible for cellular respiration, a process that produces ATP (adenosine triphosphate) for energy. The other organelles listed, such as the nucleus, Golgi apparatus, and vacuole, have distinct functions within the cell and are not directly involved in cellular respiration. The nucleus contains genetic material, the Golgi apparatus is involved in protein processing and packaging, and the vacuole is responsible for storage and maintaining cell turgor pressure.

2. Which of the following describes a difference between cytosol and the mitochondrion?

Correct answer: C

Rationale: The mitochondrion is a membrane-bound organelle, while cytosol is the fluid part of the cytoplasm. This differentiation highlights that the mitochondrion has its own membrane structure separating it from the cytoplasm, whereas cytosol is not membrane-bound and represents the liquid portion of the cytoplasm. Choice A is incorrect because cytosol is not a membrane-bound organelle, and the mitochondrion is also not described accurately. Choice B is incorrect as cytosol is indeed part of the cytoplasm. Choice D is incorrect because both the mitochondrion and cytosol are part of the cytoplasm, but the mitochondrion is a membrane-bound organelle unlike cytosol.

3. What is the basic structural and functional unit of the kidney?

Correct answer: B

Rationale: The correct answer is B, Nephron. The nephron is indeed the basic structural and functional unit of the kidney. It is responsible for filtering blood, regulating electrolytes, maintaining fluid balance, and removing waste products. Choice A, Neuron, is incorrect as neurons are nerve cells, not specific to kidney function. Choice C, Glomerulus, is a component of the nephron but not the entire functional unit. Choice D, Axon, is a part of nerve cells and is not related to kidney structure or function.

4. What is the primary function of the small intestine?

Correct answer: B

Rationale: The correct answer is B: "To absorb nutrients." The small intestine's primary function is to absorb nutrients from digested food. It plays a crucial role in the digestion and absorption of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals, which are essential for the body's functions and energy production. Choice A, "To absorb water," is incorrect because the absorption of water primarily occurs in the large intestine. Choice C, "To store waste," is incorrect as waste is stored in the large intestine before elimination. Choice D, "To produce enzymes," is incorrect because while the small intestine does receive enzymes from other organs to aid in digestion, its primary role is not enzyme production.

5. Which cellular organelle is used for digestion to recycle materials?

Correct answer: B

Rationale: The lysosome is the correct cellular organelle used for digestion to recycle materials. Lysosomes contain enzymes that break down waste materials, cellular debris, and ingested substances. This process helps in recycling nutrients and maintaining cellular homeostasis. The Golgi apparatus is involved in processing and packaging proteins, the centrioles play a role in cell division, and the mitochondria are responsible for energy production. However, none of these organelles are primarily used for digestion and recycling of materials within the cell.
