Front

What happens when a cell is placed in a hypotonic solution?

Back

The cell will swell and may burst due to the influx of water.

Front

Why are salt and sugar considered hydrophilic substances?

Back

They can dissolve in water due to their polar nature.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, such as high temperature.

Front

What is the independent variable in an experiment?

Back

The independent variable is the one that is manipulated or controlled by the experimenter.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the difference between a hypertonic and hypotonic solution?

Back

A hypertonic solution has a higher solute concentration than the cell, causing it to shrink, while a hypotonic solution has a lower solute concentration, causing it to swell.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the significance of the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

What are constants in an experiment?

Back

Constants are the factors that remain unchanged throughout the experiment to ensure that the results are due to the independent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the one that is measured or observed in response to changes in the independent variable.
