Match the following descriptions with the correct biological molecules.

• Glycogen

• A nucleic acid that stores genetic information

• DNA

• A type of carbohydrate that stores energy

• Enzyme

• A lipid that forms cell membranes

• Phospholipid

• A type of protein that acts as a catalyst in biochemical reactions

During a science class, Evelyn learned that photosynthesis is the process by which plants convert sunlight into what?

• Oxygen

• Carbon Dioxide

• Glucose

• Water

Answer explanation

During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The primary product of this process is glucose, which serves as energy for the plant.

Emma is conducting an experiment in her chemistry class. She learns that activation energy is the minimum amount of energy required to start a chemical reaction.

• The energy required to break bonds in reactants

• The energy released during a reaction

• The minimum amount of energy required to start a chemical reaction

• The energy needed to maintain a reaction

Answer explanation

The correct choice is 'The minimum amount of energy required to start a chemical reaction' because it directly defines activation energy, which is essential for initiating a chemical reaction.

Match the following cellular processes with their descriptions:

• Translation

• The breakdown of glucose

• Cellular respiration

• The conversion of ADP to ATP and vice versa

• ADP-ATP cycling

• The synthesis of proteins

• DNA duplication

• The replication of DNA

Answer explanation

ADP-ATP cycling refers to the continuous conversion of ADP to ATP and vice versa, which is essential for energy transfer in cells. The other options involve different biological processes not related to this cycling.

Match the following processes with the required elements in cells.

• Protein synthesis requires?

• Nitrogen

• Photosynthesis requires?

• Carbon dioxide

• Water formation requires?

• Hydrogen

• Cellular respiration requires?

• Oxygen

Answer explanation

Aerobic respiration is a metabolic process that requires oxygen to produce energy. It uses oxygen to convert glucose into carbon dioxide and water, making oxygen the essential component for this process.

Emma is learning about anaerobic respiration: Respiration without oxygen producing less ATP.

• Respiration

• Photosynthesis

• Fermentation

• Oxidation

Answer explanation

The correct choice is 'Respiration' as it refers to the process of producing energy without oxygen, which is anaerobic respiration. This process yields less ATP compared to aerobic respiration.
