Cellular energy test
What is the goal of photosynthesis
to make glucose
What is the equation for cellular respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
What are autotrophs?
Organisms that make their own food
Describe how photosynthesis and cellular respiration are opposite processes.
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
How are the products of the light dependent reactions carried over to the light independent reactions?
The Calvin cycle
Which are the reactants and which are the products of the photosynthesis equation?
carbon dioxide and water (the reactants) into glucose and oxygen (the products).
Which molecule from glycolysis is needed for the Kreb's cycle to begin?
pyruvic acid
How much ATP does glycolysis produce?
2 ATP
How much ATP does the Krebs cycle produce?
2 ATP
How much atp does electron train sport chain make
2 atp
What are the outputs of fermentation
2 lactate or 2 alcohol and 2 CO2
What is the equation for photosynthesis
6CO2 + 6H2O ------> C6H12O6 + 6O2
What products from the light dependent reactions are needed to start the light independent reactions?
ATP and NADPH
How does ATP work?
ATP has adenosine and is attached to three phosphates. It donates one o two phosphate to release energy to become ADP or AMP.
What is ATP?
Adenosine Triphosphate - ENERGY - is required for active transport.
What is the organelle and pigment used by plants for photosynthesis?
Chlorophyll
Why are plants green
Chlorophyll reflects green light
Explain the light dependent stage
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy
Explain the light-independent reactions stage
In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
Why is fermentation important?
It regenerates NAD+ so glycolysis can continue.
What is fermentation?
Making ATP w/out oxygen
From where do cells get energy
Mitochondria
Why do cells need energy?
To Live, grow, and reproduce
How much ATP does cellular respiration generate?
Together, glycolysis, the Krebs cycle, and the electron transport chain release about 36 molecules of ATP per molecule of glucose.
When does fermentation occur?
absence of oxygen
Two types of fermentation
alcoholic and lactic acid
Where does glycolysis occur?
cytoplasm
What are the steps of cellular respiration
glycolysis, krebs cycle, electron transport chain
Where does the electron transport chain occur?
inner membrane of mitochondria
Where does the Krebs cycle occur?
mitochondrial matrix in eukaryotes
What are heterotrophs?
organisms that cannot make their own food
