2. Photosynthesis

3. Photosynthesis Definition –
Equation – (carbon dioxide) (water) (glucose) (oxygen)
CONVERTING SUN’S ENERGY INTO FOOD ENERGY (GLUCOSE)
CO H20 + LIGHT C6H12O6 + O2
Photosynthesis

4. 2 Steps of Photosynthesis
CO2 O2
Goal of the Light Dependent reaction: __________________________________________________
Goal of the Light Independent reaction: _____________________
Make energy (ATP) to power the Calvin cycle
Make glucose

Grana – entire stack
Stroma – white space
6. How do plants absorb light?
Notice the stacks inside of the chloroplast. These stacks absorb sunlight. This arrangement increases the amount of ________________________ to absorb as much sunlight as possible.

6. Pigments PIGMENTS ABSORB REFLECT REFLECTS GREEN PHOTOSYNTHESIS
Plants contain _____________________ that _______________ some wavelengths of light and ________________ others.
ABSORB
REFLECT
For example, if a plant appears red, the plant ________________ this color. ______________________ is one of the most abundant pigments in a plant which absorbs the red and blue colors of the spectrum and reflects ________________ which is what makes plants appear green. The light plants absorb is used to undergo __________________________.

11. 3. 2 Types Cellular Respiration:
(Best Option) ____________________________ Respiration
If ___________________ is present, the cell may continue ATP production by going through aerobic respiration. Aerobic Respiration is most commonly used and preferred because much more ATP can be produced.
The equation for aerobic respiration is:
_________ + _________  ________ + _______ + ___ATP
AEROBIC
OXYGEN
C6H12O O CO H
GLUCOSE OXYGEN CARBON WATER
DIOXIDE

12. 3 Steps of Aerobic Respiration

13. 2. (Other option) Respiration
When is NOT present, also called
Two types of fermentation
1. ________________________ Fermentation occurs in yeast.
Equation: __________ ________ + _____ + ____ ATP
These ingredients are used to make many foods:
In _______________, yeast releases _____________________ - which is what adds holes or air bubbles to your bread
The alcohol produced by yeast is utilized in ________________.
ANAEROBIC

14. Lactic Acid Fermentation - occurs in cells when they run out of .
Equation: ______________ __________________ + _____ ATP
When you are exercising really hard your muscles use up their ATP and oxygen sot the muscle cells begin to produce ATP through lactic acid fermentation.
