Photosynthesis
The process used by plants where the energy of sunlight is used to convert water and carbon dioxide into oxygen glucose.
Photosynthesis
an aerobic process that releases energy by breaking down glucose and other food.
Cellular Respiration
Where do Light Dependent reactions take place?
They take place in the Thylakoids
What takes place in Step 1 of Photosynthesis?
Sunlight excites the electrons in Photosystem 1.
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.
What are the 2 processes of Photosynthesis?
Light Dependent Reactions and Light Independent Reactions (Calvin Cycle)
What are the 3 stages of Cellular Respiration?
The 3 stages of Cellular Respiration are Glycolysis, Kreb's Cycle and the Electron Transport Chain.
Where does the Calvin Cycle take place?
The Calvin Cycle takes place in the Stroma.
In which step does NADP+ hold 2 high energy electrons and a H+ ion?
Step 4 of Photosynthesis.
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.
What 3 things affect the rate of Photosynthesis?
temperature, availability of water and the light intensity.
What occurs in Cellular Respiration if the conditions are anaerobic(no oxygen)?
If the conditions are anaerobic then Fermentation occurs.
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.
What occurs in Step 2 of Photosynthesis?
The electrons gain energy and they need a special carrier to transfer their energy to another molecule.
In what stage are the end products 32 molecules of ATP and H₂O?
The Electron Transport Chain
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.
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.
Which of these 2 processes occurs first, Light dependent reactions or Calvin cycle?
The Light Dependent Reactions occur first, and its products are used in the Calvin Cycle.
Which 2 stages are Aerobic?
The Kreb's Cycle and Electron Transport Chain
What is the equation for Photosynthesis?
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ or carbon dioxide + water → glucose(sugar) + oxygen
The arrow in the equation represents the light energy that is required for photosynthesis to take place.
What is the equation for Cellular Respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
or
Glucose + oxygen → carbon dioxide + water + ATP
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.
Which process occurs in the Matrix of the Mitochondria?
The Kreb's Cycle.
