Biology- Cellular Respiration

Front

What is glycolysis?

Back

Glycolysis is the process in which glucose (sugar) is broken down into pyruvate, producing a small amount of energy (ATP) in the absence of oxygen.

Front

What is the role of mitochondria in cellular respiration?

Back

Mitochondria are known as the 'powerhouse of the cell' because they produce ATP, the energy currency of the cell, through processes like the Krebs cycle and oxidative phosphorylation.

Front

Why does the body require vitamins and minerals?

Back

The body requires vitamins and minerals because it cannot produce enough of them on its own, and they are essential for various biochemical processes.

Front

What is ATP synthesis?

Back

ATP synthesis is the process of producing adenosine triphosphate (ATP) from ADP and inorganic phosphate, primarily occurring in the mitochondria during cellular respiration.

Front

What is a vitamin?

Back

A vitamin is an organic compound that is essential for normal growth and nutrition, required in small quantities in the diet because the body cannot synthesize them.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP, which powers cellular activities.

Front

What is aerobic respiration?

Back

Aerobic respiration is a form of cellular respiration that requires oxygen to produce ATP, involving glycolysis, the Krebs cycle, and oxidative phosphorylation.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a form of cellular respiration that occurs without oxygen, resulting in the production of energy and byproducts like lactic acid or ethanol.

Front

What is the difference between aerobic and anaerobic respiration?

Back

The main difference is that aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
