Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy and building blocks for growth.

Front

Why do cells need molecules from food?

Back

Cells need molecules from food to obtain energy, build cellular structures, and perform essential functions.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is essential for cellular respiration as it helps break down glucose to release energy.

Front

What is the relationship between glucose and energy production?

Back

Glucose is a primary source of energy for cells; it is broken down during cellular respiration to produce ATP, the energy currency of the cell.

Front

How does altitude affect oxygen availability for exercise?

Back

At high altitudes, there is less oxygen available, which can make it harder for the body to perform aerobic activities.

Front

What are amino acids and why are they important?

Back

Amino acids are the building blocks of proteins; they are essential for growth, repair, and maintenance of body tissues.

Front

What happens to food molecules during digestion?

Back

During digestion, food molecules are broken down into smaller units (like glucose and amino acids) that can be absorbed and used by the body.

Front

What is the significance of starch in the diet?

Back

Starch is a complex carbohydrate that provides a significant source of energy when broken down into glucose.

Front

How do cells use oxygen and glucose to produce energy?

Back

Cells use oxygen and glucose in a process called cellular respiration to produce ATP, carbon dioxide, and water.

Front

What is the impact of low glucose levels on exercise performance?

Back

Low glucose levels can impair exercise performance because cells need glucose to produce sufficient energy.
