EQ: What are we made of?

Front

What happens to a balloon full of maple syrup when placed in a glass of water over time?

Back

The balloon will become large because water diffuses into it due to osmosis.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes work by decreasing the activation energy of the reaction.

Front

What does it mean for an enzyme to be denatured?

Back

Denaturation refers to when an enzyme no longer functions because its shape has changed.

Front

What is surface tension in relation to water molecules?

Back

Surface tension is the cohesive force between water molecules.

Front

What are the four main types of macromolecules?

Back

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

Front

Define osmosis in biological terms.

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What role do enzymes play in biological reactions?

Back

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

Front

What factors can lead to enzyme denaturation?

Back

Factors such as extreme temperatures, pH changes, and the presence of certain chemicals can lead to enzyme denaturation.

Front

Explain the concept of cohesion in water molecules.

Back

Cohesion refers to the attraction between water molecules due to hydrogen bonding, which contributes to surface tension.

Front

What is the significance of macromolecules in living organisms?

Back

Macromolecules are essential for various biological functions, including structure, energy storage, and information transfer.
