How many reactions are there in photosynthesis?
Two photosynthetic reactions. Photosynthesis involves two sets of chemical events, termed the light and dark reactions. This terminology is somewhat misleading, because the entire process of photosynthesis is regulated to take place when an organism absorbs visible light. The light reactions refer to the set of reactions in which the energy ...
Where does photosynthesis begin?
Photosynthesis begins with the absorption of light in the thylakoid membrane. The energy of the light makes a difference in its effect on photosynthesis. The following considerations can help you understand this concept. The energy of a single photon of light is inversely proportional to its wavelength, with the visible region ...
How does chlorophyll differ from other tetrapyrroles?
Chlorophylls differ from other tetrapyrroles by possessing a long, branched phytol joined to the tetrapyrrole in an ether linkage. The phytol is an “anchor” to keep the chlorophyll inside the thylakoid membrane. Photosynthesis begins with the absorption of light in the thylakoid membrane. The energy of the light makes a difference in its effect on ...
What is the green color of chloroplasts?
The green color of the chloroplast (and therefore plants) comes from the chlorophyll that is stored in them. Chlorophyll is a tetrapyrrole ring system with a Mg2+ ion in the center, coordinated to the nitrogen of each pyrrole ring. The tetrapyrrole ring system is found as a bound cofactor (a prosthetic group) in many electron‐carrying proteins, enzymes, and oxygen transporters. For example, tetrapyrroles are essential to the functioning of cytochrome c, various mixed function oxidases, and hemoglobin. Chlorophylls differ from other tetrapyrroles by possessing a long, branched phytol joined to the tetrapyrrole in an ether linkage. The phytol is an “anchor” to keep the chloro phyll inside the thylakoid membrane.
Where do light and dark reactions occur in plants?
In higher plants, both the light and the dark reactions take place in the chloroplast, with each reaction set occurring in a different substructure. In electron micrographs, the chloroplast is seen as a series of membranes that come together to form grana, or grains, set in the stroma, or spread‐out region as seen in Figure . Within the grana, the membranes stack upon each other in a disk‐like arrangement called the thylakoid. Each region of the chloroplast is specialized to carry out a specific set of reactions. The light reactions occur in the grana and the dark reactions occur in the stroma.
What is the energy that is converted into glucose in photosynthesis?
Photosynthesis converts carbon from carbon dioxide to glucose with reducing equivalents supplied from water and energy supplied from light. The energy in light is dependent on its wavelength, and is given by the following relationship. The Greek letter nu, ν, stands for the frequency of the light, h is a constant called Planck’s constant, ...
How do dark reactions work?
The dark reactions use this reducing power and energy to fix carbon, that is, to convert carbon dioxide to glucose. Biochemically, converting CO 2 to glucose without light is possible if a supply of reducing equivalents and ATP are available.
What is the process of photosynthesis?

Further, the photosynthetic efficiency is the fraction responsible for converting into chemical energy in the duration of the photosynthesis method. Moreover, it occurs in plants and algae. Photosynthesis can be described by the simple chemical reaction given below:
What are the two reactants that make up the food?
Algae, plants and photosynthetic bacteria take in light through the sun, water molecules from their environment and carbon dioxide from the air and combine these reactants to produce the food i.e. glucose. Of course, light, water and carbon dioxide mix up in the air even without the plants.
When do we use chemical reactions?
We use chemical reactions every time we are cooking or baking. After that, we add the ingredients together (the reactants), place them in a suitable specific condition (often heat), and then enjoy the result that it gives (the products). The photosynthesis reaction is shown below:

How does chlorophyll absorb light energy?
Chlorophyll absorbs the light energy from the sun to split water molecules into hydrogen and oxygen. The hydrogen from water molecules and carbon dioxide absorbed from the air are used in the production of glucose. Furthermore, oxygen is liberated out into the atmosphere through the leaves as a waste product.
Where does light energy come from in photosynthesis?
Light energy is absorbed by chlorophyll molecules whereas carbon dioxide and oxygen enter through the tiny pores of stomata located in the epidermis of leaves. Another by-product of photosynthesis is sugars such as glucose and fructose. These sugars are then sent to the roots, stems, leaves, fruits, flowers and seeds.
