B9 (Respiration) Flashcards
1
Q
Equation for Aerobic respiration
A
Oxygen + Glucose -> Carbon Dioxide + Water
2
Q
Test for Co2
A
Limewater passed through Co2 turns cloudy
3
Q
Parts of the cell for respiration
A
- cytoplasm where enzymes are made
- nucleus code for enzymes
- mitochondria enzymes for respiration
- cell membrane gas can move freely in the cell
4
Q
5 uses of energy from respiration
A
- amino acids build up sugars and nitrates for protein
- build larger molecule for cell material
- mineral ions move to root hair cell
- muscles contract
- maintain constant body temperature
5
Q
Why do you breathe heavily after exercise?
A
- muscles contract more often so need more oxygen and glucose
- increase the volume of blood to get to the muscles which contains the oxygen
6
Q
Glycogen
A
- stored in your muscles and converts back to glucose
- supply for cellular respiratiom
7
Q
Anaerobic respiration equation for animals
A
Glucose -> lactic acid
8
Q
Anaerobic respiration equation for plants and fungi
A
Glucose -> ethanol + Carbon Dioxide
9
Q
Why does Anaerobic respiration occur
A
When the oxygen supply is running out
10
Q
Consequence of Anaerobic respiration + explanation
A
- build up of lactic acid in the muscles, oxygen is needed to remove it (why we breathe heavily after exercise)
- blood transport this back to the liver
- converted back to glucose or glycogen
- oxygen dept re-payed
11
Q
6 metabolic reactions
A
- glucose to starch, glycogen and cellulose
- formation of lipid molecules from glycogen and fatty acid molecules
- amino acid
- photosynthesis in plants
- breakdown of proteins in the liver to form urea for excretion
12
Q
4 roles of the liver
A
- passing waste products
- breaking old red blood cells and storing iron for new
- deamination (break down of proteins)
- detoxifying poisonous substances (like Ethanol)
