Anatomy and Physiology Test 1 EXAM 2025 – 2026 Review GRADED A+
QUESTIONS WIT H CORRECT ANSWERS GRADED A+
Carbohydrates and proteins are built up from their basic building blocks by
the ________.
removal of a water molecule between each two units
Which of the following best defines anatomy?
It is the study of the structure of body parts and their relationships with one another.
Which of the following statements is not one of the four major concepts of the
cell theory?
The function of a cell dictates the chemical structure and organelles of the cells.
How would a small, nonpolar molecule likely diffuse across a cell membrane?
simple diffusion
What is the difference between active and passive transport across the plasma
membrane?
Active transport is ATP dependent, whereas passive transport uses only the kinetic
energy of the particles for movement across the plasma membrane.
What is a membrane potential?
a voltage or electrical charge across the plasma membrane
Which of the following organelles is correctly paired with its function?
smooth endoplasmic reticulum: metabolism of lipids
Which of the following correctly states the functions of the rough endoplasmic
reticulum?
synthesis of cellular membrane components
As you look under a microscope you see a nucleus with a large density of
nucleolus. What inference can you make about that cell?
The cell is producing a large amount of proteins.
What must happen before a body cell can begin mitotic cell division?
Its DNA must be replicated exactly so that identical copies of the cell's genes can be
passed on to each of its offspring.
Which of the following names the three main parts of a human cell?
, Page 2 of 9
cytoplasm, plasma membrane, and nucleus
(True or False) Phospholipids provide the cell-specific functions of the plasma
membrane.
false
Which of the following describes tight junctions?
junctions among epithelial cells lining the digestive tract
Which of the following is a component of the plasma membrane that creates a
physical barrier between the inside and the outside of the cell?
phospholipids
Ions are transported across plasma membranes using __________, which
requires __________.
channel-mediated facilitated diffusion; kinetic energy
Assume that Na+ is being transported across a membrane via facilitated
diffusion. Which of the following conditions would allow for the most transport
of Na+ across that membrane?
Na+ diffusing toward the side of the membrane with Cl− and 50% less Na+
Drinking alcohol can cause dehydration, which makes the blood hypertonic.
Which option best describes the consequences of this hypertonic blood?
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial
fluid hypertonic. This, in turn, draws water out of the cells.
(True or False) Channel-mediated diffusion is a form of active transport.
false
Which of the following is a difference between primary and secondary active
transport?
In primary active transport, the transport protein gets phosphorylated; in secondary
active transport, the transport protein is not phosphorylated.
Which of the following processes allows cells to concentrate material that is
present only in very small amounts in the extracellular fluid?
receptor-mediated endocytosis
(True or False) In their resting state, all body cells exhibit a resting membrane
potential; therefore, all cells are polarized.
True
What can we infer if we see a large number of mitochondria in a cell?
The cell has a great metabolic demand.
