Final Review Unit 2

Front

What is the effect of temperature on respiration rate according to biological principles?

Back

As temperature increases, the respiration rate typically increases due to enhanced enzyme activity.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, and it is green in color.

Front

True or False: DNA can be consumed from plant and animal sources.

Back

True, DNA can be consumed from various living organisms, including vegetables, fruits, and meats.

Front

What is the main product of glucose breakdown during cellular respiration?

Back

The complete breakdown of glucose during cellular respiration yields ATP molecules.

Front

What are the monomers that make up lipids?

Back

Lipids are made up of glycerol and fatty acids.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

Explain the relationship between enzyme activity and temperature.

Back

Enzyme activity generally increases with temperature up to a certain point, after which it may denature and decrease.

Front

What is ATP and why is it important for cells?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What are the two main stages of cellular respiration?

Back

The two main stages of cellular respiration are glycolysis and the citric acid cycle (Krebs cycle), followed by oxidative phosphorylation.
