Glucose——-> lactic acid
Anaerobic respiration in plants
Glucose——-> ethanol+ carbon dioxide

What does Rose black spot do?
Leaves turn black and drop
No growing or photosynthesis
How do you prevent rose black spot?

How is rose black spot spread?
Water and wind
Word equation for aerobic respiration
Glocuse + oxygen ——> carbon dioxide + water
How do organism use energy from respiration?
.Build larger molecules from small ones e.g protein from amino acids
.Muscular contraction to move
.Maintain body temperature
What is the word equation for anaerobic respiration in plants and yeast?
Glucose —> ethanol + carbon dioxide
Why do we not want to do anaerobic respiration?
.Not efficient -Incomplete breakdown of glucose because there is no oxygen to oxidise
.Lactic acid build up which needs to be removed (burning sensation)
