Aerobic Respiration
Syllabus
Define aerobic respiration as the chemical reactions in cells that use oxygen to
break down nutrient molecules to release energy
State the word equation for aerobic respiration as glucose + oxygen → carbon
dioxide + water
Investigate the uptake of oxygen by respiring organisms, such as arthropods and
germinating seeds
RESPIRATION
Respiration is a chemical reaction that happens
in all our cells to release energy.
This can be used for – Contraction of muscle
cells, producing movement – Active transport of
molecules and ions – Building large molecules,
such as proteins – Cell division
The reaction also releases some heat which is
used to maintain steady body temperature
Respiration: Aerocic and anaerobic
RESPIRATION
Your cells can carry out two types of respiration.
One with oxygen which is called aerobic respiration and one without oxygen called
anaerobic respiration.
glucose + oxygen → carbon dioxide + water
C6H12O6 + 6O2 → 6CO2 + 6H2O
ANAEROBIC RESPIRATION
Respiration without oxygen
ANAEROBIC RESPIRATION IN YEAST
Also known as FERMENTATION.
Yeast cells are single celled fungi.
Used for commercial purposes such as brewing.
Glucose Ethanol + Carbon Dioxide (+ some energy)
ANAEROBIC RESPIRATION IN MUSCLE
Occurs when the blood cannot reach the muscles fast enough to supply them with
the required oxygen.
