Word equation for anaerobic respiration in animals
Glucose——-> lactic acid
Anaerobic respiration in plants
Glucose——-> ethanol+ carbon dioxide
What are pathogens?
Microorganisms that can cause disease
What is Athletes foot?
Fungus
How can pathogens be spread?
Contaminated food and water
Air (tiny droplets)
Direct contact
How can you prevent disease?

What does TMV do?
Discoloured leaves and mosaic pattern
Less photosynthesis to produce glucose and grow
What is Rose black spot?
Fungus
What does Rose black spot do?
Leaves turn black and drop
No growing or photosynthesis
How do you prevent rose black spot?
Fungicides
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)
How is lactic acid converted Back to glucose?
The blood carries the lactic acid from muscles to liver to convert back to glucose
