What is energy?
Energy is the ability to do work
When is work done?
Work is done when a body is moving
Respiration is…
Respiration is the release of energy from food
What are the two types of respiration?
Aerobic and anaerobic
What is the release of energy from food when oxygen is not present?
Anaerobic respiration
What is the release of energy from food in the presence of oxygen?
Aerobic respiration
What is respiration often called?
A biochemical process
Why is respiration a biological process?
Because it occurs in living cells
Why is respiration a chemical process?
Because new substances are formed by chemical reactions
What processes is respiration?
Chemical and biological
What factors are necessary for respiration?
Glucose
Oxygen
Correct temperature
What is word equation for aerobic respiration?
Glucose + oxygen —> Energy + carbon dioxide + water
What is the chemical equation for aerobic respiration?
C6H12+ 602 —–> energy + 6CO2 + 6H2O
What is the word equation for Anaerobic respiration?
Glucose —–> energy + lactic acid
What are the factors that affect respiration?
Glucose availability
Oxygen availability
Temperature
Why does temperature affect respiration?
Enzymes (proteins that control all biochemical processes) require a certain temperature to work, if the temperature is too high or too low the enzyme will be destroyed.
What experiment did you do for this chapter?
Glucose and yeast are placed in 4 test tubes, the test tubes are then placed in water baths at different temperatures. The result is based on how much foam is in the container.
