When is fat stored in our bodies?

When we eat more calories than we need

What does food provide for the body?

Building materials

How do kids grow taller by eating food?

They build larger molecules to make new cells

Why aren’t vitamins and minerals food?

Because they don’t provide us with energy

What two types of energy did the burning tortilla chip release when burned?

Light energy and Thermal energy

Why do we get so hot and sweaty when we exercise?

Because our body needs to burn food more quickly so you have the energy to run

Cellular Respiration

It is the process by which cells in plants and animals break down sugar and turn it into energy.

What does Cellular Respiration provide our bodies with?

Thermal energy and Kinetic Energy

Photosynthesis

Plants use this process to take the light energy (sun) and convert it into chemical energy to store glucose molecules and oxygen.

What is the chemical reaction for Photosynthesis?

6CO₂      +        6H₂O             →      C₆H₁₂O₆      +           6O₂

(Carbon Dioxide) + (Water) (Glucose) + (Oxygen)

What do plants use their roots for?

Plants use their roots to take in nutrients (vitamins & minerals) and water from the soil

What is the chemical reaction for Cellular Respiration?

C₆H₁₂O₆      +           6O₂      →          6CO₂            +        6H₂O   + energy

(Glucose + Oxygen) (Carbon Dioxide + Water + Energy)
