Transfer of Matter and Energy

How different types of cells get energy to do cellular work!

Transfer of Energy and Matter

What do cells need energy for?

What types of energy works best for cellular work?

Which energy storing molecule is best if you want to put money in the bank for later? Which is the best if you want to get a gumball from a machine?

Glycogen/Starch vs. Glucose vs. ATP

ATP Battery

• “Charged”=ATP• “Dead”=ATP• Can be recharged by

enzymes!

How do ALL living things make ATP energy?

• Cellular Respiration

• BOTH plant and animal cells use this process

Formula for Making ATP

(ATP!!!)

Efficiency: Depends on use of O2

• Aerobic: with oxygen– Plants, animals,

protists– More efficient at

making ATP• Anaerobic: without

oxygen– Some Bacteria and

fungi– Less efficient at

making ATP

Organelle necessary for aerobic cellular respiration=mitochondria

3 parts of Aerobic cellular respiration

Glycolysis 2ATP

Krebs Cycle 2ATP

Electron Transport Chain 34ATP

How is the human body organized to get the materials to make ATP to its body’s cells?

• What does a muscle cell need to make ATP?– Oxygen

– Glucose

• What body system’s bring this material to the cells?– Digestive System

– Respiratory System

– Circulatory System

Anaerobic…Fermentation

• Only 2 ATP total per a glucose!• Two types:

– Alcoholic– Lactic Acid

Practice It!

• BioCoach Activity--This is your classwork today and your homework after your next test. Do each module (#1-6). Take notes on each section, notes should total no more than 2 sides of a page! Try to pick out what’s important using the activities to help.
