Cell RespirationUnit Target:Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and

oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy .

Learning Target: Define cellular respiration. (Knowledge)

True or False?

Cellular respiration releases energy from food.

True

The type of energy formed during cellular respiration is glucose.

False- ATP

The two types of cellular respiration are _______________and _____________.

Anaerobic and Aerobic

The two reactants of aerobic cellular

respiration are ( glucose / pyruvate )

and ( oxygen / water ).

Which is the correct equation for aerobic cellular respiration?

a. oxygen + sugar ---- carbon dioxide + water + Energy

b. oxygen + sugar + Energy ---- carbon dioxide + water

c. Carbon dioxide + water ---- oxygen + sugar + Energy

d. Carbon dioxide + water + Energy ---- oxygen + sugar

a.

What type of energy is produced by cellular respiration?

ATP and heat

When (carbon dioxide / oxygen ) is not

present after glycolosis, the cell will carry

out anaerobic respiration which can also

be called ( fermentation / photosynthesis ).

Which type of fermentation is it?

sugar- alcohol + carbon dioxide

Alcohol fermentation

sugar- lactic acid

Lactic acid fermentation

Which fermentation results in sore muscles?

Lactic acid- muscles don’t work well when they don’t get oxygen and are bathed in lactic acid.

Learning Target: Compare and contrast cellular respiration and photosynthesis.

(reasoning)Which process is it?

Produces glucose

Requires oxygen

Creates 34-38 ATP

Occurs in plants and animals

Photosynthesis

Aerobic cellular respiration

Summary

True or False?Most organisms depend on the sun as a source of energy.

True

Autotrophs are the only organisms that can convert the sun’s energy to usable chemical energy in a process called photosynthesis.

True

Both autotrophs and heterotrophs release the energy stored in foods such as glucose in a process called cellular respiration.

True
