1.6 the energy circle of life

mitochondria: respiration => producing energy from glucose with oxygen

Chloroplasts: fotosynthesis => making glucose and oxygen from carbon dioxide and water using sunlight 

Respiration

Getting energy from food 

• Our fuel is glucose
  
• Oxygen is needed to break down glucose (breathing)
  

The gas produced during respiration

1. CO2
2. O2
3. H2O
4. N

During respiration glucose is broken down to release

1. Water
2. CO2
3. Energy
4. Oxygen

What is the formula of respiration? 

->

Glucose

Oxygen

Energy

Carbon dioxide

Water

WHAT IS THE NAME OF THE PROCESS PLANTS DO TO MAKE SUGARS FROM SUNLIGHT?

1. CHLOROPLASTS
2. RESPIRATION
3. PHOTOSYNTHESIS
4. DIGESTION
