Respiration - Coggle Diagram
Respiration
Aerobic respiration
Release energy with OXYGEN
Glucose + oxygen --> carbon dioxide + water (+ energy)
Exothermic reaction
Use it for metabolism
Or transferred as thermal energy to surroundings
Happens in mitochondria
Anaerobic respiration
Releasing energy WITHOUT oxygen
Animals: Glucose --> latic acid (+energy)
Energy is released faster
Good for short bursts of energy e.g. sprinting
Other organisms
Glucose --> carbon dioxide + ethanol
Bacteria : glucose --> lactic acid
Used to make yogurts
Yeast: Glucose--> carbon dioxide + ethanol
Carbon dioxide used to make bread rise
Release of energy
Why do we need to?
Muscle contraction
Skeletal muscles
Heart
Diaphragm
Digestive system - stomach, intestines
Active transport
Moving substance from a low to a high concentration
Maintain a consent body temperature
e.g. humans 37 degrees
Metabolism (chemical reactions)
e.g photosynthesis
e.g. digestion - breaking down larger molecules into smaller ones
e.g. Synthesis (building up molecules)
Exercise
Muscles are contracting harder and faster this requires more energy
Heart rate increase
Pumps more blood with O2 and glucose to go to muscle cells
Breathing rate increases
Oxygen into the lungs fatsr s it can diffuse into the blood
Also helps to remove CO2
Glycogen is broken down into glucose for respiration
If doing anaerobic respiration muscles will be in oxygen debt
The amount of oxygen needed to brake down lactic acid
Lactic acid transported to liver
Converted into glucose
Use it for aerobic respiration
After exercise keep high breathing a high heart rate
