UExcel Anatomy and Physiology Test — Questions and Answers
Question 1: Which of the following is not true when the body is positioned in the anatomical position?
- The palms are facing backward (Correct answer)
- The body is erect.
- The face is forward.
- The arms are at the sides.
Correct answer: The palms are facing backward
The correct answer: <br> The palms are facing backward
Question 2: Which of these is not a hydrophilic substance?
- Lipids (Correct answer)
- Nucleic acid
- Carbohydrates
- Proteins
Correct answer: Lipids
Explanation: <br> Lipids are hydrocarbon-containing compounds that serve as the structural and functional building blocks of living organisms.
Question 3: True/False: The wrist is distal to the elbow.
- False (Correct answer)
- True
Correct answer: False
Explanation: <br> The wrist joint is located far away from the elbow joint. The proximal row of carpal bones houses the scaphoid. The ankle joint is close to the knee joint.
Question 4: Which of the following lists best exemplifies the concept of rising complexity levels?
- Organelles, cells, tissues, organs, systems (Correct answer)
- Cells, tissues, organelles, organs, systems
- Tissues, cells, organs, organelles, systems
- Organs, organelles, systems, cells, tissues
Correct answer: Organelles, cells, tissues, organs, systems
The correct answer: <br> Organelles, cells, tissues, organs, systems
Question 5: What is the link between the thoracic cavity and the abdominopelvic cavity?
- Superior (Correct answer)
- Inferior
- Dorsal (posterior)
- Ventral (anterior)
Correct answer: Superior
Explanation: <br> The rib cage surrounds the thoracic cavity, the superior subdivision of the anterior cavity. The lungs and the heart, positioned in the mediastinum, are housed in the thoracic cavity. The diaphragm separates the thoracic cavity from the inferior abdominopelvic cavity by forming the thoracic cavity's floor.
Question 6: The citric acid cycle includes:
- 2 ATP's form
- Carbon dioxide is released
- Hydrogen atoms are released
- All of the above (Correct answer)
Correct answer: All of the above
Explanation: <br> The citric acid cycle integrates glucose, fat, and protein metabolism. The cycle's processes are carried out by eight enzymes, which totally oxidize acetate (a two-carbon molecule) in the form of acetyl-CoA into two carbon dioxide and water molecules apiece.
Question 7: How do living organisms use oxygen?
- It is used to release energy that is stored in food. (Correct answer)
- It controls the amount of heat produced.
- It is part of water and is necessary to keep organisms hydrated.
- Its a source of energy.
Correct answer: It is used to release energy that is stored in food.
Explanation: <br> Oxygen assists organisms in growing, reproducing, and converting food into energy. Humans receive oxygen by breathing into their lungs through their nose and mouth. Our cells use oxygen to break down food and obtain the energy we require to exist.
Question 8: Lipids are produced in:
- The smooth endoplasmic reticulum (Correct answer)
- The liver
- The Golgi apparatus
- The rough endoplasmic reticulum
Correct answer: The smooth endoplasmic reticulum
Explanation: <br> The endoplasmic reticulum (ER) produces structural lipids, which are then actively transferred to the membranes of other organelles.
Question 9: A decomposition reaction can be represented as:
- A+B -->AB
- AB-->A+B (Correct answer)
- C+D-->AB
- A+B --> C+D
Correct answer: AB-->A+B
Explanation: <br> AB-->A+Bis a common symbol for a decomposition reaction, where AB is the substrate and A and B are the products.
