Question 7

What is the formula for cellular respiration (Mitochondria are responsible for releasing the energy from sugar. This is the process of cellular respiration)?

Answer 7

Glucose + Oxygen = Energy + Water + Carbon Dioxide

C6 H12 o6 + 6o2 = Energy + 6H20 + 6CO2

Question 8

Plants make their own sugar in a process called photosynthesis. In plants, photosynthesis makes the sugar, and then cellular respiration releases the energy from it.
What is the formula for photosynthesis?

Answer 8

Water + Carbon Dioxide + Sunlight > Glucose + Oxygen

H20 + CO2 Sunlight > C6 H12 O6 + O2

Question 9
