Term
Where is the genetic information of the cell stored?
Definition
nucleus
Term
The structural framework in a cell is the
Definition
cytoskeleton.
Term
Where in a cell is ATP made?
Definition
mitochondria
Term
What carries instructions for making proteins from the nucleus into the cytoplasm?
Definition
mRNA
Term
One of the ways smooth endoplasmic reticulum (ER) differs from rough endoplasmic reticulum is that rough ER is covered by
Definition
ribosomes.
Term
Which of the following is part of the endomembrane system?
Definition

Golgi apparatus

 The endomembrane system includes the ER, the Golgi apparatus, lysosomes, and vesicles. It manufactures, processes, and transports lipids and proteins. The Golgi apparatus processes and packages proteins.

Term
Which of the following organelles breaks down worn-out organelles?
Definition
lysosomes
Term
Where are lipids made in the cell?
Definition
smooth endoplasmic reticulum (ER)
Term
What structure acts as a selective barrier, regulating the traffic of materials into and out of the cell?
Definition
plasma membrane
Term
Which plant cell organelle converts chemical fuel into packets of chemical energy that can power the cell?
Definition
Mitochondrion.
Term
The plant cell wall
Definition
is a protective structure made of cellulose fibrils
Term
Which of the following is a function of the central vacuole?
Definition
Storing compounds produced by the cell
Term
_____ are found only in plant cells, but _____ are found in both plant and animal cells.
Definition
Central vacuoles; ribosomes
Term
An organism gets carbon by using carbon dioxide in the atmosphere to make sugar molecules. This organism is a
Definition
producer.
Term
Which organisms play a role in returning carbon to the atmosphere?
Definition
Producers, consumers, and decomposers.
Term
Every carbon atom in the organic molecules that make up your body MUST recently have been part of
Definition
a producer.
Term
Imagine following a single carbon atom through the carbon cycle. Which of the following is a possible path for the carbon atom to take?
Definition
The atmosphere, a plant, a herbivore, a decomposer, then back to the atmosphere.
Term
Which process or processes return carbon to the atmosphere?
Definition
Cellular respiration only.
Term
Select the correct sequence of steps as energy is extracted from glucose during cellular respiration.
Definition
glycolysis acetyl CoA citric acid cycle electron transport chain
Term
What is the correct general equation for cellular respiration?
Definition
C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP energy
Term
Which of the following processes takes place in the cytosol of a eukaryotic cell?
Definition
Glycolysis, the breakdown of glucose into two molecules of pyruvic acid, takes place in the cytosol, outside the mitochondria.
Term
  In what organelle would you find acetyl CoA formation, the citric acid cycle, and the electron transport chain?
Definition
mitochondrion
Term
Which statement describes glycolysis?
Definition
This process splits glucose in half and produces 2 ATPs for each glucose.
Term
Which statement describes the citric acid cycle?
Definition
This process produces some ATP and carbon dioxide in the mitochondrion.
Term
Which statement describes the electron transport chain?
Definition
This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.
Term
In active transport,
Definition
molecules move across the plasma membrane against their concentration gradient.
Term
A molecule moves down its concentration gradient using a transport protein in the plasma membrane. This is an example of
Definition
facilitated diffusion.
Term
Water crosses the plasma membrane
Definition
through facilitated diffusion or diffusion.
Term
  The sodium-potassium pump uses energy from ATP to move sodium ions out of the cell, and potassium ions into the cell. This is an example of
Definition
active transport.
Term
The plasma membrane forms a pocket that pinches inward, forming a vesicle that contains material from outside the cell. This describes the process of
Definition
endocytosis.
