Slide 2

The Marathon

If somebody challenged you to a run a race, how should you prepare to win?

Practice

Eat the right foods

Drink the right liquids

Slide 3

All living organisms break down sugars to get energy. In humans this breakdown usually occurs with oxygen.

Slide 4

Aim

To understand how Aerobic and Anaerobic Respiration Occurs

Slide 5

SWBAT

Learn how the type of sugar affects the rate of respiration.

Learn how the concentration of sugar affects the amount of energy produced.

Determine the rate of respiration while using yeast to breakdown different sugars.

Slide 6

What is Aerobic Respiration?

The breaking down of sugar to produce energy where oxygen is present.

Glucose + Oxygen  Carbon Dioxide + Water+ Energy

Slide 7

When We Exercise…

After two minutes of exercise, the body responds by supplying working muscles with oxygen.

When oxygen is present, glucose can be completely broken down into carbon dioxide and water

Slide 8

Anaerobic Respiration refers to the oxidation of molecules in the absence of oxygen to produce energy

It is also known

As Fermentation

Slide 9

What happens when fermentation occurs?

In Muscle Cells- During extraneous activities, the oxygen in the muscle tissue is decreased to an extent that aerobic respiration does not occur at a sufficient rate. Hence, there is a buildup of lactic acid and your muscles get tired

2. In Yeast- The fermentation end product is ethyl alcohol, and CO2

Slide 10

Energy + Glucose

Ethanol + Carbon Dioxide + Energy

Chemical Formula for Anaerobic Respiration

Slide 11

Lab Experiment

We will be testing four different drinks to see which will give us the most energy

Slide 12

So how do we decide which is best?
