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.
