The document compares aerobic and anaerobic respiration, outlining their shared characteristics as well as their differences in efficiency and ATP production. It also discusses the roles of copper and iron ions in electron transport and oxygen transport during respiration. Additionally, it explains how excess acidity in the stomach can be reduced through the use of bases like aluminum hydroxide, magnesium hydroxide, magnesium carbonate, and sodium bicarbonate in antacids. These bases neutralize stomach acid through neutralization reactions.

B.9 Respiration
B.9.1. Compare aerobic and anaerobic respiration of glucose in
terms of oxidation/reduction and energy released.
B.9.2. Outline the role of copper ions in electron transport and
iron ions in oxygen transport.
3. +
B.9.1
Shared characteristics of aerobic and anaerobic respiration:
Produce ATP (chemical energy)
Glycolysis (converting glucose to pyruvate)
Oxidation reaction
Pyruvate (CH3COCOOH)
Exothermic
5. +
Anaerobic Respiration
Does not require oxygen
Only produces 2 mol of ATP for every 1 mol of glucose
consumed
Pyruvate is reduced to lactic acid (C3H6O3)
C6H12O6 ---> 2C3H6O3

B.9.2
Electron Transfer Chain (ETC): Couples electron transfer (ET)
between donors and acceptors with H+ ion transfer across a
membrane.
Cytochromes: Made of hemes. Carries out ET
Example: Cytochrome c oxidase (copper ions)
Active site that is occupied by copper.

B.9.2
Iron acts as a transporter of oxygen through hemoglobin
Fe2+ oxides to Fe3+ when it bonds to O2
Oxygen turns into superoxygen
One molecule of hemoglobin can carry
4 molecules of oxygen (4 heme groups)

D.2.1. State and explain how excess acidity in the stomach can
be reduced by the use of different bases.

Gastric Acid
pH between 1.5-3.5. Composed of HCl
Bicarbonate: the body’s antacid

D.2.1
Antacids can be combined with other compounds
Alginates
Anti-foaming agents
Alginates prevent heartburn by creating a neutralizing layer that
prevents acid reflux
Anti-foaming agents like dimethicone help relieve bloating which is a
symptom of acid reflux
-Maalox would be an example
