The 5 Steps of Photosynthesis
3 stages of Cellular Respiration
100
What is Photosynthesis?
The process used by plants where the energy of sunlight is used to convert water and carbon dioxide into oxygen glucose.
100
What is Cellular Respiration?
Cellular Respiration is an aerobic process that releases energy by breaking down glucose and other food.
100
Where do Light Dependent reactions take place?
They take place in the Thylakoids
100
What takes place in Step 1 of Photosynthesis?
Sunlight excites the electrons in Photosystem 1.
100

What are the first, second and third stages of Cellular Respiration?

1) Glycolysis

2) Kreb's Cycle

3) Electron Transport Chain.

200
What are the 2 processes of Photosynthesis?
Light Dependent Reactions and Light Independent Reactions (Calvin Cycle)
200
What are the 3 stages of Cellular Respiration?
The 3 stages of Cellular Respiration are Glycolysis, Kreb's Cycle and the Electron Transport Chain.
200
Where does the Calvin Cycle take place?
The Calvin Cycle takes place in the Stroma.
200
In which step does NADP+ hold 2 high energy electrons and a H+ ion?
Step 4 of Photosynthesis.
200

What happens in Glycolysis, and what is required for this?

Glucose is broken down into 2 pyruvates. Cells have to use 2 molecules of ATP for this stage. The end products of Glycolysis are 4 molecules of ATP and 2 NADH.

300
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.
300
What occurs in Cellular Respiration if the conditions are anaerobic?
If the conditions are anaerobic then Fermentation occurs.
300
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.
300
What occurs in Step 2 of Photosynthesis?
The electrons gain energy and they need a special carrier to transfer their energy to another molecule.
300
In what stage are the end products 32 molecules of ATP and H₂O?
The Electron Transport Chain
400
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.
400
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.
400
Which of these 2 processes occurs first?
The Light Dependent Reactions occur first, and its products are used in the Calvin Cycle.
400
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.
400
Which 2 stages are Aerobic?
The Kreb's Cycle and Electron Transport Chain
500
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.
500
What is the equation for Cellular Respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
500
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.
500
What are the special carrier molecules required in Step 2 of Photosynthesis?
NADP+ is the special carrier molecule required in step 2.
500
Which process occurs in the Matrix of the Mitochondria?
The Kreb's Cycle.
