What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms 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, carbon dioxide, and water.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, and it is not found in animal cells.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 37°C for many human enzymes.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used in cellular respiration to help convert glucose into energy, producing carbon dioxide and water as byproducts.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that captures light energy for photosynthesis.
