Gas Exchange

Front

What is gas exchange?

Back

Gas exchange is the process by which oxygen is taken in and carbon dioxide is released by living organisms, primarily occurring in the lungs of animals and the leaves of plants.

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, where energy is extracted from nutrients through cellular respiration, producing ATP.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

How does respiration differ from photosynthesis?

Back

Respiration is the process of breaking down glucose to release energy, while photosynthesis is the process of creating glucose using sunlight.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is essential for aerobic respiration, allowing cells to produce ATP efficiently.

Front

What happens to brain cells without oxygen?

Back

Without oxygen, brain cells cannot make enough ATP, leading to cell damage or death.

Front

What type of cells require the most oxygen?

Back

Liver cells require the most oxygen due to their high metabolic activity and energy demands.

Front

What is the function of chloroplasts?

Back

Chloroplasts are the cell structures in plants where photosynthesis occurs, converting light energy into chemical energy.

Front

What is the relationship between respiration and energy production?

Back

Respiration is the process that converts biochemical energy from nutrients into ATP, which is used for energy in cellular activities.
