Amplify Unit 2: Metabolism Review

Front

What is metabolism?

Back

Metabolism refers to the set of life-sustaining chemical reactions in organisms that convert food into energy and building blocks for growth, maintenance, and repair.

Front

What are the two main types of metabolism?

Back

The two main types of metabolism are catabolism (the breakdown of molecules to obtain energy) and anabolism (the synthesis of all compounds needed by the cells).

Front

What role do glucose molecules play in cellular respiration?

Back

Glucose molecules are a primary source of energy for cells; they react with oxygen to produce ATP (adenosine triphosphate), which powers cellular activities.

Front

Why is oxygen important for exercise?

Back

Oxygen is crucial for aerobic respiration, which generates energy efficiently during prolonged physical activity. Without sufficient oxygen, energy production is limited.

Front

What happens to energy production when glucose levels are low?

Back

When glucose levels are low, cells cannot produce enough ATP, leading to fatigue and decreased exercise performance.

Front

How do starch molecules relate to glucose?

Back

Starch is a polysaccharide made up of glucose units. When digested, starch is broken down into glucose, which can then be used for energy.

Front

What is the significance of amino acids in metabolism?

Back

Amino acids are the building blocks of proteins and are essential for various metabolic processes, including tissue repair and enzyme function.

Front

What can low levels of oxygen in cells indicate?

Back

Low levels of oxygen in cells can indicate respiratory issues, which can impair the ability to perform aerobic metabolism and exercise.

Front

How does the digestive system affect energy levels?

Back

The digestive system breaks down food into smaller molecules (like glucose and amino acids) that can be absorbed and utilized by cells for energy.

Front

What is the relationship between exercise and energy production?

Back

Exercise increases the demand for energy, which requires adequate levels of glucose and oxygen for efficient ATP production.
