Presentation Transcript

(autotrophs)

CO2 + H2O C6H12O6 + O2

Carbon dioxide Glucose &

& water oxygen

Respiration

(heterotrophs)

What is the function of photosynthesis?

- Energy storage
Converts light energy to chemical energy in the form of glucose.

What are the two stages of photosynthesis?

Light Calvin

Reactions Cycle

requires light

light independent

What is the formula for glucose?

- C6H12O6

Where in the cell does photosynthesis take place?

- Thylakoid membranes ofchloroplasts.

Where in the chloroplast does the Calvin cycle take place?

- Grana of chloroplast

What is the equation for Photosynthesis?

- 6CO2 + 6H2O → C6H12O6 + 6O2

What are the reactants of Photosynthesis?

- CO2 and H2O

What are the products of Photosynthesis?

- C6H12O6 and O2

What is the function of Cellular Respiration?

- Energy release
Breaks down glucose to form ATP for cellular activities

Cellular Respiration

Glycolysis (yields ATP)

AerobicAnaerobic

(oxygen) (w/o oxygen)

fermentation

Yields 21- 36 Yields 2 ATP

ATP

Anaerobic Respiration

Alcohol Lactic Acid

Fermentation Fermentation

Alcohol & CO2 Lactic acid + CO2

baking, sours milk,

brewing muscle fatigue

What is glycolysis and where does it take place?

Glycolysis breaks down glucose into pyruvic acid in the cytoplasm

How many molecules of ATP does glycolysis produce?

- 2 molecules of ATP

How many molecules of ATP does Cellular Respiration produce?

Glycolysis 2 ATP

Aerobic + 36 ATP

Total 38 ATP

Where in the cell does Cellular Respiration take place?

- Mitochondria – 2 membrane (outer and inner folds cristae)

Energy Release/Storage Cycle

ATP= Adenosine Tri Phosphate (A-P-P-P)

ADP = Adenosine Di Phospate (A-P-P)

A-P-P - P

energy energy

storage release

A-P-P + P

What is the equation for Cellular Respiration?

- C6H12O6 + 6O2 → 6CO2 + 6H2O (+ Energy in
form of ATP)

What are the reactants of Cellular Respiration?

- C6H12O6 and O2

What are the products of Cellular Respiration?

- CO2 and H2O
