What are the chemical events in photosynthesis and describe each?
Three major events occur in plant cells during photosynthesis: (1) absorption of light energy, (2) conversion of light energy into chemical energy, and (3) storage of chemical energy in sugars. Those three events occur in two distinct but interdependent sets of reactions.
What is chemically happening during photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
What are the two events of photosynthesis?
Two events that occur during photosynthesis are : (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen.
What is the first event in 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.
Why photosynthesis is a chemical reaction?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.
What is the photosynthesis process step by step?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
What are the three events that occur during photosynthesis?
The three 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.
Which is the chemical equation for the process of photosynthesis?
Following is the chemical equation for the process of photosynthesis: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2
What is the role of stomata in photosynthesis?
Stomata play an important role during the process of photosynthesis. The exchanging of gases takes place with the help of stomata. Following is the chemical equation for the process of photosynthesis: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2
