Photosynthesis has two reactions involved. What are they?
|
Light dependent reactions and Light independent reactions (Dark reactions)
|
|
|
In photosynthesis
CO2+ H2O------> ? |
Glucose
|
|
|
Radient energy (sun) produces.....
|
ATP and NADP:H
|
|
|
ATP and NADP:H from solar energy react with CO2 to form
|
A 3 carbon sugar
|
|
|
The inside of a chloroplast is known as...
|
stroma
|
|
|
A stack of thylakoids are known as ?
|
Granum
|
|
|
The connection between two Granum is called
|
stroma thylakoid
|
|
|
The inside space of a thylakoid is known as the
|
thylakoid lumen
|
|
|
In photosynthesis, the three carbon sugar that is produced from ATP and NADP:H reacting with CO2 is eventually converted to...
|
Starch
|
|
|
What is the goal of the light dependent phase of photosynthesis?
|
to produce ATP and 2 NADPH
|
|
|
What type of light is reflected by Chlorophyll molecules?
|
green light
|
|
|
What are chlorophyll molecules composed of and why are they composed of this?
|
Lipids. This is so chlorophyll molecules can be held firmly within the membrane
|
|
|
When protons from light strike a chlorophyll molecule what happens to an electron?
|
It moves to a higher energy state
|
|
|
What are the 4 things that can occur when an electron jumps from the ground state to an excited state?
|
Energy can be transferred
Give off light Give off heat- if drop bak down |
|
|
How is energy transferred from one chlorophyll molecule to the next?
|
When each electron goes from a high energy state back down to ground state
|
|
|
What are the reaction center p680 and p700
|
this refers to the maximum wave length chlorophyll molecules can absorb
|
|
|
What is the term given for the transfer of energy from one chlorophyll molecule to the next?
|
inductive resonnence
|
|
|
Where do electrons come from that replace electrons lost in the the reaction center p680, in Photosystem II?
|
From the splitting of the H2O molecule that is split into 1/2 O2 and 2 H
|
|
|
Where in the cell does Photosystem I and Photosystem II occur?
|
In the thylakoid membrane
|
|
|
When electrons from p680 are at a higher energy level where does it go?
|
To p700 reaction center
|
|
|
What happens to electrons when p700 is struck by photons of light?
|
Electrons become excited and use NADP + 2H to form NADP:H OR it returns back down to p700 ground state.
|
|
|
This produces ATP from substrate level phosphorylation as hydrogen moves accross the concentration gradient from hi to lo concentration first entering the Cf0
|
ATPase Cf1
|
|
|
Electrons that are at a higher level from the p700 reaction center produce NADPH. When electrons flow back to p700 ground state after being excited by photons, what affect happens?
|
hydrogens are pumped across membrane through Cfo to make more ATP`
|
|
|
What is required in the light Independent phase?
|
NADP:H and CO2 and ATP
|
|
|
What is produced in the light independent phase?
|
a three carbon sugar
|
|
|
What is the most abundant enzyme in the world?
|
Ribulose Bisphosphate Carboxylate
|
|
|
How many carbons are present in Ribulose bisphosphate?
|
5 carbons
|
|
|
How many carbons is in 3-Phosphoglycerate?
|
3 carbons
|
|
|
There are 15 carbons total from 3 molecules of this enzyme
|
Ribulose bisphosphate
|
|
|
3 molecules of Ribulose bisphosphate will give you how many carbons?
|
15
|
|
|
6 molecules of 3-phosphoglycerate will give you how many carbons?
|
18
|
|
|
how is 3 molecules of Ribulose bisphosphate converted to 6 molecules of 3-phosphoglycerate?
|
This is done through the input of 3 CO2
|
|
|
how is 6 molecules of phosphoglycerate (3c) reduced to 6 molecules of Glyceraldehide 3 phosphate?
|
the input of ATP, releasing ADP
the input of NADPH, releasing NADP |
|
|
in the calvin cycle, 6 molecules of glyceraldehyde 3 phosphate becomes 5 molecules of G3P. What does five molecules of G3P become and what are the inputs and outputs?
|
It becomes 3 molecules of Ribulose 1, 5 Bisphosphate. Input of 3 atp and output of 3 adp.
|
|
|
what allows 3 molecules of Ribulose 1, 5 bisphosphate to become 6 molecules of Phosphoglycerate?
|
The input of 3CO2 and also through the enzyme Rubisco Bisphosphate Carboxylase
|
|
|
This is the central dogma of cell biology
|
info flow in cells
|
|
|
Swiss physician, discovered nuclein in WBC's. today it is known as dna that he found. Who was he and what year was this?
|
1869 Miescher
|
|
|
Dealt with S and R bacteria that were injected into mice. The shocking discovery was that... when heat killed s strain bacteria was injected along with living r bacteria the mice died because of transformation of R strain into S strain. Who was he and what year was this imoportant?
|
frederick griffith 1928
|
|
|
in frederick griffith's experiment. what does s and r represent?
|
s=smooth. this was w/ capsul
r= rough. no capsul |
