The diagram below shows how food is
processed in an organism.
The letter X most likely represents
1) Digestion
3) ATP
2 )Synthesis
4) Energy
The diagram represents a
biochemical process.
Which molecule is represented by X?
(1) Oxygen
(3) protein
(2) starch
(4) ATP
A biological process that occurs in both plants and animals is shown below.
Which row in the chart below identifies the lettered substances in this process?
A small water plant
(elodea) was placed in
bright sunlight for five
hours as shown.
Bubbles of oxygen gas
were observed being
released from the plant.

A sample of food containing one type of a
large molecule was treated with a specific
digestive enzyme. Tests show the products of
the enzyme catalyzed reaction are simple
sugars, only. Based on these test results, the
original large molecules contained in the food
sample were molecules of
(1) protein
(2) glucose
(3) starch
(4) lipid (fats)
Which phrase, if placed in box X, would correctly
complete the flowchart shown below?
(1) Increased use of starch in root cells
(2) Increased concentration of glucose in leaf cells
(3) Decreased ATP in root cells
(4) Decreased concentration of oxygen in leaf cells
The diagram
represents
part of a
cellular
process .
Energy is released and made available for
metabolic activities at
1) step 1, only
2) step 2, only
3) both step 1 and step 2
4) neither step 1 nor step 2
The diagram
represents
processes that occur
in the chloroplasts
of plant cells.
Which set of terms best identifies the letters
in the diagram below?
By which process is the stored energy of
organic molecules transferred to a form
of energy that is usable by cells?
1) digestion
3) photosynthesis
2) aerobism
4) respiration
Much of the carbon dioxide produced by
green plants is not sent away as a
metabolic waste because it
(1) can be used for photosynthesis
(2) is too large to pass through cell
membranes
(3) is needed for cellular respiration
(4) can be used for the synthesis of proteins
The diagram here represents a
process that occurs in a structure
of a specialized cell.
Which row in the chart
correctly identifies the
letters in the diagram?
The diagram shows
a laboratory set-up
used by students in
a biology class.
After a day, what is a likely observation a student may make?
1. The solution outside the membrane will change to white
2. The solution outside the membrane will change to yellow
3. The solution inside the membrane will change to yellow
4. The solution inside the membrane will change to black
