Aerobic and aerobic respiration. Flashcards
Chemical reactions inside cells are controlled by…
enzymes.
During aerobic respiration, chemical reactions occur that…
Use glucose and oxygen.
Produce useful energy that’s released to ‘power’ the cells.
Aerobic respiration takes place in both…..
Plants and animals.
Where do most reactions for aerobic respiration take place?
The mitochondria of cells.
Equation for aerobic respiration
Glucose+Oxygen==>Carbon dioxide+water(+energy)
How can energy made in aerobic respiration be used in cells?
To build larger molecules e.g proteins to amino acids.
To enable muscles to contract and relax.
To maintain a steady body temperature in colder surroundings.
To build up from sugars, nitrates and other nutrients and amino acids(in plants).
The more you move your muscles…
The more oxygen you need for respiration.
The more vigorous the exercise, the…….the heart rate.
Greater.
During exercise the body goes into…
anaerobic respiration.
Explain oxygen dept
When your body goes into anaerobic respiration it doesn’t receive enough oxygen to function properly and has to ‘re-pay’ the debt by increasing breathing rates.
the changes in breathing rates mean…
Blood flow to muscles increases and therefore the supply of sugar and oxygen for energy from respiration. Also it increases the rate of removal of carbon dioxide(a waste product).
Muscles store glucose as
Glycogen.
Glycogen in converted back to……during exercise
Glucose.
Word equation for anaerobic respiration
Glucose==>lactic acid+energy.
The build up of lactic acid can cause…
Cramps/ muscle fatigue.
