EOC Prep 2: Water, Macromolecules, Enzymes, PS and CR

Front

What is the optimum pH of an enzyme?

Back

The optimum pH of an enzyme is the pH at which it exhibits maximum activity. For example, an enzyme may have an optimum pH of 6.6.

Front

Where does cellular respiration occur in a cell?

Back

Cellular respiration occurs in the mitochondria of the cell.

Front

What is the relationship between enzymes and activation energy?

Back

Enzymes decrease the activation energy of a reaction, making it easier for the reaction to occur.

Front

What type of organic molecule is a waxy coating on plants that reduces water loss?

Back

The waxy coating is a lipid.

Front

How does temperature affect enzyme function?

Back

Enzymes function best at a specific temperature, typically around the normal body temperature of 98.6 degrees Fahrenheit.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including proteins, lipids, carbohydrates, and nucleic acids.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is 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 do enzymes play in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
