What is the role of oxygen in cellular respiration?

Back

Oxygen is essential for cellular respiration as it helps convert glucose into energy (ATP) in the presence of oxygen.

Front

What happens to cells when there is a lack of oxygen?

Back

Cells cannot produce enough energy, leading to cell damage or death.

Front

What is glucose and why is it important for the body?

Back

Glucose is a simple sugar that is a primary energy source for the body's cells.

Front

What is the respiratory system responsible for?

Back

The respiratory system is responsible for taking in oxygen and expelling carbon dioxide.

Front

What is the digestive system's role in metabolism?

Back

The digestive system breaks down food into nutrients, including glucose, which is then absorbed into the bloodstream.

Front

What are amino acids and their role in the body?

Back

Amino acids are the building blocks of proteins, essential for growth, repair, and metabolism.

Front

What can happen if there is too much glucose in the bloodstream?

Back

Excess glucose can lead to increased heart rate and, over time, may cause health issues like diabetes.

Front

What is the function of the circulatory system?

Back

The circulatory system transports oxygen, nutrients, and hormones to cells and removes waste products.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.
