Practice Science TEAS Test Questions

Question 1 of 5

What is the end product of glycolysis?

Correct Answer: D

Rationale: The correct answer is D: Pyruvic acid. In glycolysis, glucose is broken down into pyruvic acid. This process generates ATP and NADH as well. Lactic acid (A) is produced in anaerobic conditions, not at the end of glycolysis. ATP (B) is produced during glycolysis but is not the end product. NADPH (C) is not the end product of glycolysis, it is produced in the pentose phosphate pathway.

Question 2 of 5

What is the primary function of the kidneys?

Correct Answer: B

Rationale: The correct answer is B: To filter blood and produce urine. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain the body's balance of fluids and electrolytes. This process is essential for regulating blood pressure, producing hormones, and maintaining overall bodily function. Choices A, C, and D are incorrect because the kidneys are not involved in digesting food, absorbing nutrients, or transporting oxygen.

Question 3 of 5

Which of the following is another name for a sweat gland?

Correct Answer: C

Rationale: The correct answer is C: Sudoriferous. Sudoriferous glands are commonly known as sweat glands. These glands are responsible for producing sweat, which helps regulate body temperature. "Ceruminous" glands produce earwax, "Sebaceous" glands produce oil, and "Integumentary" refers to the skin as a whole, not specifically to sweat glands. Therefore, the correct choice is C.

Question 4 of 5

What is the primary mode of CO2 transport in the body?

Correct Answer: A

Rationale: The correct answer is A: Bicarbonate. CO2 is primarily transported in the blood as bicarbonate ions. This process involves carbonic anhydrase converting CO2 into carbonic acid, which then dissociates into bicarbonate and hydrogen ions. Bicarbonate is the main form in which CO2 is transported from tissues to the lungs for elimination. Choice B, carbamino compounds, refers to CO2 bound to amino groups in hemoglobin, but this method is a minor mode of CO2 transport. Choice C, None of these, is incorrect as bicarbonate is indeed the primary mode of CO2 transport. Choice D, Plasma, is incorrect as CO2 is not directly transported in the blood as plasma but rather in the form of bicarbonate ions.

Question 5 of 5

Which part of the brain regulates body temperature, hunger, and thirst?

Correct Answer: B

Rationale: The correct answer is B: Hypothalamus. The hypothalamus regulates body temperature, hunger, and thirst through its control of the autonomic nervous system and hormonal systems. It plays a crucial role in maintaining homeostasis. The cerebellum (A) is responsible for coordination and balance, the thalamus (C) acts as a relay station for sensory information, and the medulla oblongata (D) regulates vital functions such as breathing and heart rate, but not body temperature, hunger, or thirst.
