- Energy from respiration
- Aerobic respiration
- glucose + oxygen = carbon dioxide + water (+energy)
- testing for carbon dioxide from respiratoin
- blow carbon dioxide through limewater until it goes cloudy
- mitochondria - site of respiration
- folded inner membrane to give large SA for enzymes in respiration
- more mitochondria = more active cell
- why?
- living cells need energy to carry out basic functions of life
- build large molecules from small
- building / synthesis reactions
- amino acids into proteins
- animals, energy is used to make muscles contract
- homeostasis
- living cells need energy to carry out basic functions of life
- The effect of exercise on the body
- muscles
- made of protein fibres
- contract when supplied with energy
- store glucose as glycogen
- converted back rapidly during exercise
- use energy even when not moving
- response to exercise
- heart rate increase, arteries supplying blood widen
- increases blood flow to muscles
- increases oxygen and glucose to muscles and carbon dioxide from muscles
- increases blood flow to muscles
- breathing rate increases, and deeper breathing
- more often, more air
- more oxygen brought round body by red bloodcells
- more carbon dioxide out. transfer of gases is quicker everywhere
- more often, more air
- heart rate increase, arteries supplying blood widen
- more exercise = heart and lunges larger
- more efficient blood supply
- muscles
- Anaerobic respiration
- Aerobic respiration
