IB SEHS Topic 3.3

AKA “anaerobic glycolysis," this system breaks down glucose into pyruvate and lactic acid.

This happens to energy when an ATP molecules loses its endmost phosphate group

During a muscle contraction, chemical energy, supplied by breakdown of ATP, is converted into

Anaerobic cell respiration produces up to how many molecules of ATP?

Match the correct energy system with the type of athlete it benefits the most.

Animal cell organelle that controls the functions of the cell and contains DNA.

Wrinkled fold in the inner membrane of mitochondrion that provides large surface area.

Consists of 1 adenosine and 3 phosphates, this molcule provides energy for muscle contraction.

This process requires oxygen to form 38 ATP molecules per glucose molecule metabolized.

Animal cell organelle where energy is extracted from during metabolism.

Identify label C.

oxygen consumed during exercise -oxygen consumed if aerobic respiration occurred immediately.

Part of mitochondrion that functions with the inner membrane allowing proteins to enter matrix.

Identify label B.

Energy system that provides sufficient energy for endurance athletes.

excess post-exercise oxygen consumption (“EPOC”), demand for oxygen is greater than the supply

Energy system that provides contraction of high power/short burst activities.

Identify label C.

The controlled release of energy, in the form of ATP, from organic compounds in cells.

Identify label F.
