Metabolism Chapter 2

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy.

Front

What are the two main types of metabolism?

Back

The two main types of metabolism are catabolism (breaking down molecules to release energy) and anabolism (building up molecules using energy).

Front

What is the role of glucose in metabolism?

Back

Glucose is a simple sugar that is a primary source of energy for cells during metabolism.

Front

What is the function of the digestive system?

Back

The digestive system breaks down larger food molecules into smaller molecules that can be absorbed by the body.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, which are essential for growth and repair in the body.

Front

What happens to starch in the digestive system?

Back

Starch is broken down into smaller glucose molecules by enzymes in the digestive system.

Front

What is the circulatory system's role in metabolism?

Back

The circulatory system transports nutrients, including glucose, from the digestive system to cells throughout the body.

Front

Why is oxygen important for metabolism?

Back

Oxygen is essential for aerobic respiration, a process that helps convert glucose into usable energy.

Front

What is the relationship between the digestive and circulatory systems?

Back

The digestive system breaks down food into nutrients, and the circulatory system transports these nutrients to cells.

Front

What can happen if starch molecules are not broken down properly?

Back

If starch molecules are not broken down, they cannot enter cells, leading to fatigue and lack of energy.
