Vocabulary
Aerobic
With oxygen
**SPIN THAT WHEEEEEL!
The inputs for photosynthesis
What are carbon dioxide and water?
(Sunlight is used as a form of ENERGY but is not a "reactant")
Where does respiration happen?
Where does photosynthesis take place? Be specific.
Chloroplasts of plant cells
Anaerobic
Without oxygen
a. Name the main pigment in plants.
b. What color(s) of light does this pigment absorb?
a. Chlorophyll
b. blue and red
Products of cellular respiration
What are ATP, carbon dioxide, and water?
**SPIN THAT WHEEEEEL!
Teams who guessed correctly, add 200. Teams that guess incorrectly subtract 200
Fermentation
A type of anaerobic respiration
**SPIN THAT WHEEEEEL!
The products of photosynthesis
What are glucose and oxygen?
**SPIN THAT WHEEEEEL!
Describe how energy changes form during respiration
Chemical energy in glucose changes to chemical energy in ATP
**SPIN THAT WHEEEEEL!
Describe the relationship between photosynthesis and cellular respiration.
The products of one are used as the reactants of the other (almost) and vice versa
(The difference is that photosynthesis has an input of sunlight energy and cellular respiration has an output of ATP energy)
Chlorophyll
Pigment in chloroplasts that absorbs sunlight
Photosynthesis Equation
6CO2+6H2O ---(sunlight)---> C6H12O6 + 6O2
6 Carbon dioxide + 6 Water ---(sunlight)---> 1 Glucose + 6 Oxygen
Reactants for cellular respiration
What are oxygen and glucose?
The body's muscle cells can start to burn during intense exercise due to
Lactic acid fermentation
**SPIN THAT WHEEEEEL!
Starch
Polysaccharide (Long chain of glucose molecules); Plants store glucose in the form of starch (They just make long chains out of their extra glucose)
The main purpose of photosynthesis
To convert light energy into chemical energy within the bonds of glucose
**SPIN THAT WHEEEEEL!
The cellular respiration equation
C6H12O6 + 6O2 ---> 6CO2 + 6H2O + ATP
1 Glucose + 6 Oxygen ---> 6 Carbon dioxide + 6 Water + ATP
Why do leaves turn orange/yellow in the fall?
Chlorophyll breaks down- xanthophylls and carotenes become the main pigments in plants (reflect yellow-orange light)
Organic
Carbon and hydrogen; typically large molecules
Examples include: Carbohydrates, proteins, nucleic acids, lipids
Describe how energy changes form during photosynthesis
Light energy to chemical energy in the bonds of glucose
How does the body obtain the reactants for cellular respiration?
1. Oxygen: Breathing
2. Glucose: Eating carbohydrates
ATP is "usable" energy for cells. List three (3) things that cells/living things may do with this ATP energy.
1. Growth
2. Development
3. Reproduction
4. Chemical reactions
