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
