Biology- Photosynthesis
How do animal cells store glucose for later? How do plants store glucose for later?
1. Cellulose - cell wall and plant 2. Strach - storage energy - storage energy 3. Glvogen- animals, stored sugar in animal cell. Liver plus muscle
Be able to label the parts of a chloroplast and tell where the reactions for photosynthesis happen
1. Thylakoid - light independent 2. Storms light independent reaction 3. Granum
What are the 2 mins of chlorophyll?
A + B
Equation that shows how ADP is changed into ATP
ADP + P + energy is ATP
Equation how ATP is changed into ADP
ATP - P is ADP + energy
Which molecule produced by the light independent reaction are used during the Calvin cycle
ATP, oxygen, NADHP
What is an autotroph? A heterotroph? Give examples
An organism that makes its own food, organism that doesn't make its own food (uses energy)
Which wavelength of light are the best absorbed by chlorophyll a & b? Which are reflected?
Blue and red; green
How and where are ATP and NAPH made?
Both made in the thylakoid membrane - ATP
Which factors affect the rate of photosynthesis and how
Brightness of light, Color of light, how much CO2
Write the chemical equation for photosynthesis
Co2 + H2o light o2 + C6 H12 O6
What happens during the Calvin cycle
Co2 molecules will be remodel to make glucose, from the water that is broken down
Where does the carbon and oxygen in glucose ultimately come from
From the co2 - water
Which molecule is used by living things to store and transfer energy
Glucose
Which molecule stores more than 90 times the energy in ATP? How are these cell used
Glucose, molecules
What was "wrong" about the van helmont's conclusion that when plants grow, their increase in mass comes from water
Grew in mass size because the soil made the plant bigger, process of photosynthesis creating the plant to grow
Be able to tell the scientists
Jan van helmont, Jan ingenhousz, Joseph priestly, Melvin Calvin
Identify the molecule that participate in the light dependent reaction and tell what they do
Light dependent in photosynthesis 2 goes up to photosynthesis 1
Describe the 2 sets of reactions involved in photosynthesis
Light independent and Calvin cycle
What is another name for the Calvin cycle
Light independent reaction
Which reactions in photosynthesis require light? Which do not?
Light independent reaction, Calvin cycle
Give reactant and products for each of the reaction
Light, co2, NASPH - glucose, oxygen, Calvin cycle
Where are they located and what happens in each
Lights absorbed, electrons get exited, heading to photosynthesis one. Join an electron carrier and makes NADP - goes to the light independent- stroma attached to NADP now makes NADPH
Why does photosystem 2 come before photosystem 1 in the light dependent reaction
Marvin calvin was wrong
What is a pigment? Why is the main pigment used by green plants to absorb energy?
Molecule that absorbs light energy. Cloraphl- used blue and red light
What is NADP? What does it do? How does it change into NADPH
NADPH is an electron carrier molecule, carries exited electrons to the stroma used in the Calvin cycle. Ex: little kids energy
How are carotene pigments different from chlorophyll? Fwy do plants have these other pigments besides chlorophyll? Why do plants look green
Orange, yellow, some reds. To help the plant to get more light
Which molecule is given off as a waste gas?
Oxygen
Where does the H that ends up in NADPH ultimately come from
Pick up from the water as it carries energized electrons
What are the parts of ATP molecule
Sugar (ribose) fosfate groups
Where does the hydrogen in glucose ultimately come from
Water
What happens to water during the light reaction
Water is split into two molecules
