How does sugar yield in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
How does photosynthesis work AP Bio?
AP Biology Photosynthesis is a chemical process with the following equation: H2O + CO2 → C6H12O6 + O2. Both plants and photosynthetic bacteria are capable of this complex conversion process. The overall reaction is spurred by the energy from a photon of light striking a pigment in the chloroplast.
What is the sugar building phase of photosynthesis?
In the Calvin cycle, carbon atoms from CO2start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
What are the 7 steps of photosynthesis?
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What are the 4 main steps of photosynthesis?
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts.
- Electron Transfer.
- Generation of ATP.
- Carbon Fixation.
What happens to the sugars that are made by a plant during photosynthesis?
Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.
What happens to the sugar that plants make during photosynthesis quizlet?
plants produces glucose due to photosynthesis, then glucose gives the plant energy or stores it in the leaves. Light then is used from the sun.
At what point in photosynthesis is sugar made where does this occur quizlet?
Sugars are made in the stroma by the enzymes of the Calvin Cycle. One of a number of disk shaped membraneous sacs inside a chloroplast. Thylakoid membranes contain chlorophyll and the enzymes of the light reactions of photosynthesis. A stack of thylakoids is called a grana.
What is photosynthesis process?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What are the three steps of photosynthesis?
Photosynthesis in plants is of 3 steps, occurring in chloroplast: Absorption of light, Conversion of light energy into chemical energy and splitting of water molecules, Carbon dioxide is reduced to carbohydrates.
How do you make sugar from plants?
In the second step of photosynthesis, carbon dioxide from the air enters the leaves through very small openings. Using the previously stored chemical energy, the chloroplasts convert carbon dioxide into glucose [1]. Fructose is also produced during this step. Glucose is then combined with fructose to create sucrose.
How is sugar made in the Calvin cycle?
The Calvin cycle has two parts. First carbon dioxide is ”fixed”. Then ATP and NADPH from the light reactions provide energy to combine the fixed carbons to make sugar.
Where do we get sugar from?
Sugar is made in the leaves of the sugarcane plant through photosynthesis and stored as a sweet juice in sugarcane stalks. Sugarcane is cut down and harvested then sent to a factory.
Which is the correct order of the steps of photosynthesis?
This is a light independent reaction. Q. 1) Splitting of water molecules into hydrogen and oxygen by sunlight. 2) Absorption of light energy by chlorophyll 3) Reduction of carbon dioxide into carbohydrates.
What is the sequence of events in photosynthesis?
The events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

What are the 5 components needed for photosynthesis to occur in a plant?
- Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
- Sunlight. The process cannot work without an energy input, and this comes from the sun.
- Water.
- Carbon Dioxide.
Where do cells store sugar produced in photosynthesis?
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts — the energy factories found in plant cells.
Where is sugar stored in photosynthesis?
Trees are known to create sugar through photosynthesis; the unused sugar is transported through the phloem, stored in the trunk or roots as starch and then turned back into sugar to be used as energy again at the start of a new spring.
Where would the sugars from photosynthesis go to in a cell?
The sugar molecules made during photosynthesis travel throughout the plant. Cellular respiration happens in all cells because all of the cells need energy to stay alive. Most of the CO2 is produced in organelles called mitochondria.
What does the process of photosynthesis produce quizlet?
“the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food; Plants capture energy from sunlight during photosynthesis. This energy is used to make the sugar glucose (C6H12O6) from carbon dioxide (CO2) and water (H2O).
Which process occurs during photosynthesis quizlet?
In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
What is produced in photosynthesis quizlet?
The substances needed for photosynthesis are carbon dioxide and water. The substance produced during photosynthesis are sugars and oxygen.
How does photosynthesis transform solar energy into the chemical energy of sugar molecules quizlet?
Photosynthesis uses light energy to drive the electrons from water to their more energetic states in the sugar products, thus converting solar energy to chemical energy.
