Cellular Respiration

Its how our cells release energy from food!

BrainPOP: Cellular Respiration

Do you remember???

What types of organisms do photosynthesis?

Why do plants do photosynthesis?

What are the reactants (what goes in)?

What are the products (what goes out)?

Which plant organelle is the site of photosynthesis?

How do animals get their energy?

How do they get food?

Which organelle releases energy from food?

The process by which cells

release from glucose (sugar).

Cellular Respiration

energy

This process happens in BOTH PLANT and ANIMAL cells!

Where do plants and animals obtain glucose?

FOOD!

Animals get it from the food they eat!

Plants get it from the food they make!

Glucose is the most common

sugar found in food!

C6H12O6

Besides glucose, what else do cells use for cellular respiration?

Oxygen

How do we get oxygen?

Breathing

energy

food

oxygen

breathing

Two Stages of Cellular Respiration

Stage 1:

In the cytoplasm

Glucose is broken down into smaller molecules

A small amount of energy is released

Stage 2:

In the mitochondria

The smaller molecules react and produce carbon dioxide, water and large amounts of energy.

What are the reactants and products of cellular respiration?

C6H12O6 + 6O2 6CO2 + 6H2O + energy

+ + + glucose oxygen carbon dioxide water energy

Is matter conserved after

this chemical reaction?

Cellular Respiration Equation

Reactants (what goes in)

Products (what comes out)

This energy is also known as ATP!

Description Answers

1. Releases energy from food

2. Makes food energy for the organism

3. Performed by autotrophs (plants) only

4. Produces carbon dioxide

5. Produces glucose and oxygen

6. Occurs in the chloroplast

7. Occurs in the mitochondrion

8. Uses glucose and oxygen

9. Uses sunlight, water and carbon dioxide

10. Performed by both autotrophs (plants) and heterotrophs (animals)
