Midterm Review Quizizz Part 3

In red blood cells, carbonic anhydrase acts as which of the following? Pay attention to the suffix "ase" when answering!

• hormone

• enzyme

• lipid

• sugar

Answer explanation

Carbonic anhydrase is an enzyme that catalyzes the conversion of carbon dioxide and water to bicarbonate and protons. The suffix 'ase' indicates it is an enzyme, making 'enzyme' the correct choice.

Ovalbumin is a protein found in eggs. Which of the following best describes the molecular structure of ovalbumin?

• A. A group of six carbon atoms joined in a ring.

• B. A polypeptide chain of amino acids twisted and folded into a larger molecule.

• C. A set of three fatty acids attached to a molecule of glycerol.

• D. A sequence of nitrogen bases attached to a sugar-phosphate backbone.

Answer explanation

Ovalbumin is a protein, which means it is made up of a polypeptide chain of amino acids. This chain is twisted and folded into a specific three-dimensional structure, making option B the correct description.

Is the image above of Adenosine Triphosphate (ATP) or Adenosine Diphosphate (ADP)?

• ATP

• ADP

Answer explanation

The image depicts Adenosine Triphosphate (ATP), which has three phosphate groups. In contrast, Adenosine Diphosphate (ADP) contains only two phosphate groups. Therefore, the correct answer is ATP.

In the image above: When this molecule releases energy, the energy comes from which bond?

• The bond between A and B

• The bond between C and D

Answer explanation

The energy released by the molecule comes from breaking the bond between A and B. This bond is typically weaker or has higher energy compared to the bond between C and D, making it the source of energy release.

In which phase of photosynthesis is glucose made?

• None

• The Light Reactions

• Calvin Cycle

Answer explanation

Glucose is produced during the Calvin Cycle, which is the second phase of photosynthesis. In this phase, carbon dioxide is fixed and converted into glucose using energy from the light reactions.

Overall, what is the chemical formula for photosynthesis?

• 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

Answer explanation

The correct formula for photosynthesis is 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂, showing that water and carbon dioxide are converted into glucose and oxygen, highlighting the process of energy conversion in plants.
