What is photosynthesis?
Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms’ activities (energy transformation).
How do carboxysomes increase photosynthesis in cyanobacteria?
Cyanobacteria possess carboxysomes, which increase the concentration of CO2 around RuBisCO to increase the rate of photosynthesis. An enzyme, carbonic anhydrase, located within the carboxysome releases CO2 from the dissolved hydrocarbonate ions (HCO−. 3).
What happens in the second stage of photosynthesis?
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
What absorbs light used in photosynthesis?
Pigments absorb light used in photosynthesis. In photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis.
What are some of the solved problems on photosynthesis?
Here are a few solved problems on Photosynthesis. Problem 1: Write the complete balanced reaction for Photosynthesis both in symbol and word equation. Carbon dioxide + Water → Glucose + oxygen.
What is the general balanced reaction for photosynthesis according to Kamen?
The general balanced reaction for Photosynthesis Formula according to Kamen and Ruban (1941) is. 6CO2 + 6H2O → C6H12O6 + 6O2 + 6H2O. (Carbon dioxide) (Water) (Glucose) (Oxygen) (Water) Photosynthesis is the process of converting the energy in which solar energy is converted into the form of light which is used in the production of
What is the difference between C4 photosynthesis and Calvin cycle?
C4 photosynthesis, on the other hand, produces a four-carbon intermediate compound, which splits into carbon dioxide and a three-carbon compound during the Calvin Cycle. A benefit of C4 photosynthesis is that by producing higher levels of carbon, it allows plants to thrive in environments without much light or water.
– Types & Site Of Photosynthesis What Is Photosynthesis? “Photosynthesis is the process used by green plants and a few organisms that use sunlight, carbon dioxide and water to prepare their food.” The process of photosynthesis is used by plants, algae and certain bacteria that convert light energy into chemical energy.
What do plants need to perform photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).

What is the chemical equation for photosynthesis?
6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later. Imagine a pea plant.
What are the stages of photosynthesis in plants?
Photosynthesis has two stages: the light reaction and the carbon fixing reactions. In the light reaction the light energy is absorbed by the pigments present in the antenna, and funnelled to special chlorophyll a molecules called reaction centre chlorophylls. There are two photosystems, PS I and PS II.
What are the products of photosynthesis?
What Are the Products of Photosynthesis? What Are the Products of Photosynthesis? Chlorophyll in plant leaves converts carbon dioxide and water into the products glucose and oxygen. Connie Coleman/Getty Images
What is the ecological context of photosynthesis?
Let’s begin by placing photosynthesis in its ecological context. Photosynthesis nourishes almost the entire living world directly or indirectly. An organism acquires the organic com- pounds it uses for energy and carbon skeletons by one of two major modes: autotrophic nutrition or heterotrophic nutrition.
What are the clues to the mechanism of photosynthesis?
One of the first clues to the mechanism of photosynthesis came from the discovery that the O 2 given off by plants is URRY2751_02_C08_PR3.indd 163 01/07/15 11:08 pm # 153397 Cust: Pearson / BC Au: Urry Pg.

What are the substrates of photosynthesis?
Photosynthesis is a multi-step process that requires specific wavelengths of visible sunlight, carbon dioxide (which is low in energy), and water as substrates ( Figure 8.4 ).
What are the main structures involved in photosynthesis?
Describe the main structures involved in photosynthesis All living organisms on earth consist of one or more cells. Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis.
