Light Dependent Reactions and the Calvin Cycle
The 5 Steps of Photosynthesis
3 stages of Cellular Respiration
200
What is Photosynthesis?
The process used by plants where the energy of sunlight is used to convert water and carbon dioxide into oxygen glucose.
200
What is Cellular Respiration?
Cellular Respiration is an aerobic process that releases energy by breaking down glucose and other food.
200
Where do Light Dependent reactions take place?
They take place in the Thylakoids
200
What takes place in Step 1 of Photosynthesis?
Sunlight excites the electrons in Photosystem 1.
200
What are the first, second and third stages of Cellular Respiration?
The first stage of Cellular Respiration is Glycolysis, the second stage of Cellular Respiration is the Kreb's Cycle, which is also known as the Citric Acid Cycle, and the third cycle is the Electron Transport Chain.
400
What 3 things affect the rate of Photosynthesis?
The 3 factors that affect the rate of Photosynthesis are the temperature, availability of water and the light intensity.
400
What occurs in Cellular Respiration if the conditions are anaerobic?
If the conditions are anaerobic then Fermentation occurs.
400
Do the Light Dependent Reactions and the Calvin Cycle both require light energy to perform? Explain.
No, only the Light Dependent Reactions require light, but the Calvin Cycle requires the products produced from the Light Dependent Reactions.
400
What occurs in Step 2 of Photosynthesis?
The electrons gain energy and they need a special carrier to transfer their energy to another molecule.
400
In what stage are the end products 32 molecules of ATP and H₂O?
The Electron Transport Chain
600
What are the start and end products of Photosynthesis?
The start products of Photosynthesis are Light energy, Carbon Dioxide and Water. The end products of Photosynthesis are Oxygen and Glucose.
600
What are the 2 types of Fermentation and what do they do?
1. Alcoholic Fermentation - Yeasts use this process to form ethyl alcohol and carbon dioxide as the waste products. 2. Lactic Acid Fermentation - This occurs in bacteria and muscles when your body runs out of oxygen your muscles make ATP by fermentation and glycolysis.
600
Which of these 2 processes occurs first?
The Light Dependent Reactions occur first, and its products are used in the Calvin Cycle.
600
What is the final step of Photosynthesis?
NADP+ becomes NADPH which is then used somewhere else in the cell to build carbs such as glucose.
600
Which 2 stages are Aerobic?
The Kreb's Cycle and Electron Transport Chain
800
What are the 2 processes of Photosynthesis?
Light Dependent Reactions and Light Independent Reactions (Calvin Cycle)
800
What are the 3 stages of Cellular Respiration?
The 3 stages of Cellular Respiration are Glycolysis, Kreb's Cycle and the Electron Transport Chain.
800
Where does the Calvin Cycle take place?
The Calvin Cycle takes place in the Stroma.
800
In which step does NADP+ hold 2 high energy electrons and a H+ ion?
Step 4 of Photosynthesis.
800
What happens in Glycolysis, and what is required for this?
In Glycolysis Glucose is broken down into 2 molecules of Pyruvic Acid. Cells have to use 2 molecules of ATP for this stage. The end products of Glycolysis are 4 molecules of ATP and 2 NADH.
1000
What is the equation for Photosynthesis?
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ The arrow in the equation represents the light energy that is required for photosynthesis to take place.
1000
What is the equation for Cellular Respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
1000
What are the end products of the Light Dependent Reactions?
At the end of the Light Dependent Reactions we have chemical energy in the form of ATP and NADPH.
1000
What are the special carrier molecules required in Step 2 of Photosynthesis?
NADP+ is the special carrier molecule required in step 2.
1000
Which process occurs in the Matrix of the Mitochondria?
The Kreb's Cycle.
