Which of the following is true of the data shown in the graph?
Amylase likely lives in the human mouth since it survives well at a pH near 7.
Trypsin likely lives in the human mouth since it survives well at a pH over 7.
Pepsin most likely lives in the human mouth since it survives well at a pH over 7.
Trypsin likely lives in the human mouth because it survives well at a pH near 7.

Which of the following is an example of an anabolic pathway?
Photosynthesis builds carbohydrates from carbon dioxide and water.
Glycolysis breaks down one glucose into two molecules of pyruvate.
Sucrose is broken down into fructose and glucose
A lipid is broken down into a glycerol and fatty acid chains.
Which statement is TRUE of the first law of thermodynamics?
Energy is not created or destroyed, only changes form.
Energy is destroyed until it disappears.
Energy is always being lost to the vastness of space.
Energy can only be used, not stored.
Which of the following correctly describes a catabolic pathway?
It breaks down molecules into smaller subunits
It builds-up molecules from smaller subunits
It generates ATP
It transmits messages between cells.
Which molecule is used as the primary source of energy for cells?
NADH
sucrose
ATP
nucleic acids
____ is lost in small amounts in reactions, so entropy is always increasing.
Heat
Energy
Carbon
All of these
Chemical reactions in the human body are catalyzed when enzymes interact with substrates shown in the diagram.
What happens to the enzyme after the chemical reaction occurs?
The enzyme is used up during the reaction, so it no longer exists.
The enzyme is changed during the reaction, so it no longer works.
The enzyme becomes a part of the product of the reaction, so it no longer exists.
The enzyme is unchanged, so it can be reused when more substrate is available.
