Aerobic respiration-anaerobicrespiration
What is cellular respiration? - answer A process that releases energy from glucose for
use in cellular activities
What is the main type of cellular respiration and what does it use? - answer The main
type of cellular respiration is aerobic respiration, which uses oxygen
What is the symbol equation for aerobic respiration? - answerC6H12O6 + 6O2 → 6CO2
+ 6H2O
How much energy does anaerobic respiration release? - answer Much less energy than
aerobic respiration because the oxidation of glucose is incomplete
Describe aerobic respiration - answer Aerobic respiration is a series of chemical
reactions (requiring oxygen) that take place mostly inside mitochondria in the cell
What type of heat process is aerobic respiration? - answer Aerobic respiration is
exothermic because it releases energy. This happens continuously in living cells.
When does anaerobic respiration occur? - answerIn the absence of oxygen
How do cells get their energy? - answerAerobic respiration is the main source of energy
for cells
What is the word equation for aerobic respiration - answerglucose + oxygen -> carbon
dioxide + water (releases energy)
State the use of energy from respiration in animals - answerFrom metabolic processes
to build larger molecules from smaller ones e.g. proteins from amino acids
To enable muscle contraction
in birds and mammals to maintain steady body temperature in colder surroundings
State the use of energy from respiration in plants - answerTo build larger molecules
from smaller ones e.g. sugars, nitrates and other nutrients into amino acids, which are
then used to make proteins
The reactions of respiration are controlled by enzymes. Explain why body temperature
and pH are carefully controlled in animals - answerIs PH or temperature is too high, the
rate of reaction will slow down or even stop. This would rapidly lead to death because
respiration releases energy for essential processes in the body
