Front

What are carbohydrates made of?

Back

Carbohydrates are made of carbon (C), hydrogen (H), and oxygen (O).

Front

How do enzymes speed up chemical reactions in organisms?

Back

Enzymes decrease the energy required for a reaction to begin.

Front

What happens to the rate of a reaction when the temperature is increased from 15°C to 25°C for an enzyme with an optimal temperature of 25°C?

Back

The rate of the reaction increases.

Front

What type of biomolecule is glucose?

Back

Glucose is a carbohydrate.

Front

What binds to the active site of an enzyme?

Back

The substrate binds to the active site of an enzyme.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions.

Front

What is the structure of carbohydrates?

Back

Carbohydrates are composed of sugar molecules, which can be simple (monosaccharides) or complex (polysaccharides).

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to an optimal point, after which it may decrease.

Front

What are the three main types of biomolecules?

Back

The three main types of biomolecules are carbohydrates, proteins, and lipids.
