1.
Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production?
a)
Anaerobic cellular respiration
b)
Protein synthesis
c)
Aerobic cellular respiration
d)
photosynthesis
2.
a)
The cell membrane is an impermeable barrier that prevents water from entering the cell.
b)
The cell membrane allows solutes to enter the cell, which causes the cell to shrink.
c)
The cell membrane allows water to enter and leave the cell.
d)
The cell membrane removes solutes from the environment.
3.
Which group of organelles is directly responsible for the production of new molecules within a cell?
a)
Ribosomes, the endoplasmic reticulum, and Golgi aparatuses
b)
Golgi aparatuses, lysosomes, and the plasma membrane
c)
The endoplasmic reticulum, plastids, and vacuoles
d)
The nucleolus, vacuoles, and ribosomes
4.
The cellular process known as the sodium-potassium pump was discovered in the 1950s by Jens Christian Soku, a Danish scientist. This process is a form of active transport that moves three sodium ions to the outside of a cell for every two potassium ions that it moves into the cell. Which of these best explains why energy is needed for active transport?
a)
Ions are negatively charged.
b)
Ions are attached to large proteins.
c)
Ions are trapped inside the plasma membrane.
d)
Ions are moved against the concentration gradient.
5.
Which of these statements best explains the process of energy conversion that takes place in the mitochondria?
a)
Energy is required for carbon dioxide molecules to form six-carbon sugar molecules.
b)
Water molecules and radiant energy are necessary for anaerobic respiration to take place.
c)
Oxygen molecules release energy in the form of heat during combustion reactions.
d)
The energy in the bonds of glucose molecules is transferred to the phosphate bonds in ATP.
6.
a)
A mechanism for transforming sunlight into energy
b)
Self-locomotion
c)
Membrane-bound organelles that transport substances
d)
Genetic material composed of DNA
