Do you know?
(all sections)
100
a molecule that transfers energy from the breakdown of food molecules to cell processes
What is ATP?
100
a series of protein in the membrane of the Thylakoid
electron transport chain
100
releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present
CELLULAR RESPRIRATION
100
an anaerobic process that allows glycolysis to contiinue
fermentation
100
Where does light INdependent reactions take place
the stroma
200
A lower energy molecule that can be converted into ATP by adding a phosphate group
What is ADP?
200
Name a 6 carbon sugar molecule
GLUCOSE
200
explain the difference between aerobic & anaerobic
aerobic- needs oxygen to take place anaerobic- does not need oxygen to take place
200
where does Lactic acid occur
muscle cells,the cells of vertebrates, and in some microorganisms
200
Where does cellular respiration occur
in mitochondria
300
How are some organisms able to survive without sunlight and photosynthesis? (name the process)
CHEMOSYNTHESIS
300
Equation for photosynthesis
6CO2 + 6H2O --> --> --> C6H2O6 +6O2
300
equation for cellular respiration
C6H12O6 + 6O2 --> --> --> 6CO2 + 6H2O
300
what causes muscles to "burn" during workouts?
lactic acid
300
Where does photosynthesis occur?
chloroplasts
400
Organisms break down ______-_______ molecules to produce ATP.
CARBON-BASED
400
LIST: Light INdependent reactions A.K.A Calvin Cycle (4)steps
1.Carbon dioxide added to the 5 carbon molecules 2. 3 carbon molecules are formed and rearranged 3. 3 carbon molecules leave 4. 3 carbon molecules are recycled
400
LIST: The electron transport chain (4)STEPS
1. Electrons are removed from NADPH and FADH2 2. hydrogen ions are transported across the membrane 3. ADP is changed to ATP 4. Water forms
400
What is the over all role of fermentation?
to supply glucose with a steady supply of NAD+
400
The Kerbs cycle breaks down carbon-based molecules and transfers energy to ______ carriers
electron
500
Illustrate the ATP & ADP cycle.
*look on board*
500
list: light- DEpendent reactions (7)steps
First stage: photosystem 2 1. energy is absorbed by light 2. water molecules are broken down 3. hydrogen ions are transported across the Thylakoid Second Stage: Photosystem 1 4. energy absorbed by sunlight 5. NADPH produced 6. hydrogen ions diffuse through a protein channel 7.ATP synthase makes ATP
500
List Kerbs Cycle (6)steps
1.pyruvate broken 2.coenzyme A bonds 3.citric acid is formed 4.citric acid gets broken down 5.5 carbon molecules get broken down 6.4 carbon molecules rearranged
