Living Environment Regents DRILL 1

Front

What happens to the concentration of O2 inside a cell when it is placed in water with a higher concentration of O2 outside?

Back

The concentration of O2 will increase inside the cell due to diffusion.

Front

What are metabolic functions in a cell?

Back

Metabolic functions are the chemical processes that occur within a cell to maintain life, including energy production and synthesis of molecules.

Front

How does pH affect enzyme activity?

Back

A difference in the pH of an environment can change enzyme activity, as enzymes have optimal pH levels for their function.

Front

What is the formula to calculate total magnification in microscopy?

Back

Total magnification = eyepiece magnification x objective magnification.

Front

Why is maintaining homeostasis important for organisms?

Back

Maintaining homeostasis is crucial for regulating internal conditions, such as temperature and pH, to ensure proper functioning of biological processes.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What is the significance of temperature in enzyme activity?

Back

Temperature affects the rate of enzyme activity; each enzyme has an optimal temperature range for maximum activity.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining the internal environment.
