IB SEHS Topic 3.3

Front

What is the net amount of ATP molecules produced from one glucose molecule in the lactic acid system?

Back

2 ATP molecules.

Front

Which fuels can be used by a cell to make ATP anaerobically?

Back

Glucose is the only fuel that can be used anaerobically.

Front

What is the function of the mitochondrion in an animal cell?

Back

The mitochondrion is responsible for producing ATP through aerobic respiration.

Front

What is the function of the Golgi apparatus in an animal cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

Which energy system is the quickest to re-synthesize ATP?

Back

Creatine phosphate system.

Front

Define anaerobic glycolysis.

Back

Anaerobic glycolysis is the process of breaking down glucose without oxygen to produce ATP, resulting in lactic acid.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

Explain the difference between aerobic and anaerobic respiration.

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the primary product of anaerobic respiration in animal cells?

Back

Lactic acid.

Front

List the three main energy systems used by the body during exercise.

Back

1. Creatine phosphate system 2. Anaerobic glycolysis 3. Aerobic respiration.
