Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What gas is produced during photosynthesis?

Back

Oxygen is produced during photosynthesis.

Front

What is the role of the Calvin Cycle in photosynthesis?

Back

The Calvin Cycle produces sugar from carbon dioxide.

Front

What happens to the rate of a biochemical reaction at high temperatures?

Back

The rate of a biochemical reaction decreases at high temperatures because the shape of the enzyme changes, affecting its ability to bind to substrates.

Front

What is the function of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon dioxide back into the atmosphere and contributing to the carbon cycle.

Front

What is ATP and its role in energy storage?

Back

ATP (adenosine triphosphate) is a molecule that stores energy in its high-energy phosphate bonds, which can be released for cellular processes.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the significance of gas exchange in ecosystems?

Back

Gas exchange is crucial for maintaining the balance of oxygen and carbon dioxide in ecosystems, supporting life processes such as photosynthesis and respiration.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required.
