Cell Respiration

Topic 2.8: Cell Respiration

Essential Idea: Cell respiration supplies energy for the functions of life.

At SHS, Topic 2.8 is taught in the following class unit(s):

Anaerobic Respiration (unit 33A)
Aerobic Respiration (unit 33B)

Statements & Objectives:

2.8.U1 Cell respiration is the controlled release of energy from organic compounds to produce ATP.

Define “cell respiration.”
State the reaction for cellular respiration.
State the types of organic compounds used in cellular respiration by animals and plants.

2.8.U2 ATP from cell respiration is immediately available as a source of energy in the cell.

State three example uses of cellular energy.
Outline energy transfer in the formation and use of ATP.
State three reasons why cellular respiration must be continuously performed by all cells.

2.8.U3 Anaerobic cell respiration gives a small yield of ATP from glucose.

Define “anaerobic respiration”
List three situations in which anaerobic respiration is useful.
Compare anaerobic respiration in yeasts and humans.

2.8.U4 Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose.

Compare the total amount of ATP made from anaerobic and aerobic respiration.
State the location of aerobic respiration.

2.8.A1 Use of anaerobic cell respiration in yeasts to produce ethanol and carbon dioxide in baking.

Outline how anaerobic respiration in yeast is used in baking.
Outline how anaerobic respiration in yeast is used in ethanol production.

2.8.A2 Lactate production in humans when anaerobic respiration is used to maximize the power of muscle contractions.

State the condition in which humans would perform anaerobic respiration.
Outline production of lactate in humans during anaerobic respiration.

2.8.S1 Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer.

Outline the use of a respirometer to measure cellular respiration rate.

2.8.NOS Assessing the ethics of scientific research- the use of invertebrates in respirometers experiments.

List ethical questions that must be considered before using animals in experiments.
