Anaerobic vs. Aerobic Respiration

Do Now

With your partner: Use the slips of paper in your bag and determine if the

characteristic is a description of PHOTOSYNTHESIS or RESPIRATION

Separate them into two piles based upon their characteristics When you are done, raise your hand so I can check

When you are done: Using your notes and partner activity answer the following in

complete sentences

1. Why do animals rely on plants for survival?

2. Global warming is caused by having too many gasses such as Co2 in the air. Why might photosynthesis be helpful in reducing global warming?

What is ATP?

Adenosine TriPhosphate (ATP)Used to store and release energy.It has 3 phosphate groupsStores HIGH energy Like a: FULLY CHARGED BATTERY

What is ADP?

Adenosine DiPhosphate (ADP) It has 2 phosphate groups (rather than 3) Stores LOW energyLike a: LOW CHARGED BATTERY

How is energy released from ATP?

Energy is stored in a bond between the second and third phosphates groups.

Energy is released when the bond is broken between the 2nd and 3rd phosphate groups

In other words, energy is released when the ATP becomes ADP

How can ATP be used for energy?

ATP ADP

P

This process releases energy

How does ADP become ATP?

ADP does not have as much energy so…

ADP travels to the MITOCHONDRIA to become fully charged The 3rd Phosphate is ADDED during Cellular

Respiration

It is like: the PHONE CHARGER

How is ATP formed?

ADP + P = ATP

The chemical energy from the breakdown of glucose is used to attach “P” (a phosphate) to ADP (adenosine di-phosphate)

Where is energy stored in ATP?

Energy is stored between the 2nd and 3rd phosphate groups

Aerobic vs. Anaerobic

AEROBIC RESPIRATION

ANAEROBIC RESPIRATION

• Occurs in the presence of oxygen

• 36 ATPs are produced

•More efficient

• Occurs where there is NO oxygen

• ONLY 2 ATPs are produced

•Less efficient

• 2 types of Anaerobic Respiration: 1. Lactic Acid 2. Alcoholic Fermentation

2 Types of Anaerobic Respiration

LACTIC ACID FERMENTATION

ALCOHOLIC FERMENTATION

• Only Animals’ muscle cells

• Builds up when ATP is made with NO oxygen

• This is why your muscles get sore when you are working out hard

•EQUATION: 1 glucose CO2 + 2 ATP + LACTIC ACID

• Bacteria and yeast cells

• This is what makes bread rise!

•EQUATION:1 glucose CO2 + 2 ATP + ETHYL ALCOHOL

Respiration Stations

We will be passing around different stations.You will have ~4 minutes at each stationAt each station:

Read the station guide Use the reading to answer the questions on your

paper

Whiteboard Review

For each statement: Work with your partner to decide if it describes

AEROBIC or ANEAROBIC Hold your answer up toward the teacher when you’re

ready Communicate only with your partner!

1

C6H12O6 + 6O2 → 6CO2 + 6H20

2

C6H12O6 → 6CO2 + 6H20 + Lactic acid

3

A yeast cell produces alcohol

4

Occurs in the cytoplasm of the cell

5

Efficient ATP formation

6

A cheetah sprints toward prey and its muscle cells produce lactic acid

7

Results in the most energy stored

8

Requires the use of a mitochondrion

9

Yeast cells cause bread to rise
