Practice Science TEAS Test Questions
Question 1 of 5
Which of the following organs is responsible for producing digestive enzymes?
Correct Answer: B
Rationale: The correct answer is B: Pancreas. The pancreas produces digestive enzymes such as amylase, lipase, and proteases that help break down carbohydrates, fats, and proteins in the small intestine. The liver (A) produces bile but not digestive enzymes. The gallbladder (C) stores bile produced by the liver. The esophagus (D) is responsible for transporting food from the mouth to the stomach, not for producing digestive enzymes.
Question 2 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 3 of 5
How many neutrons and electrons could a negative ion of sulfur have?
Correct Answer: B
Rationale: Rationale: Sulfur (atomic number 16) typically has 16 protons and 16 electrons in a neutral state. A negative ion gains an electron, so it would have 16 protons, 16 neutrons, and 17 electrons to maintain charge neutrality. Therefore, choice B (16 neutrons, 17 electrons) is correct. Choices A, C, and D are incorrect as they do not account for the addition of an extra electron in the negative ion, resulting in an incorrect number of electrons.
Question 4 of 5
Which of the following molecules is a monosaccharide?
Correct Answer: B
Rationale: The correct answer is B: Glucose. Glucose is a monosaccharide because it is a single sugar molecule, the simplest form of carbohydrates. Starch (A) is a polysaccharide made up of multiple glucose units. Cellulose (C) is also a polysaccharide, not a monosaccharide. Sucrose (D) is a disaccharide composed of glucose and fructose molecules. So, only glucose (B) fits the definition of a monosaccharide in this question.
Question 5 of 5
Which of the following statements is correct based on anatomical terms?
Correct Answer: D
Rationale: The correct answer is D because anatomical terms use specific directions to describe relationships between body parts. In this case, "lateral" refers to the side of the body, so the thumb being on the lateral aspect of the hand is accurate. The other choices are incorrect because they do not follow anatomical terminology standards. Choice A incorrectly compares the shoulder joint to the neck using proximity, not specific directional terms. Choice B uses "superior" incorrectly to describe the elbow joint in relation to the shoulder. Choice C inaccurately compares the thoracic and cervical vertebrae using the term "superior," which is not anatomically correct in this context.
