Question

Explain Photosynthesis. ​

Answer 1

Explain Photosynthesis.

$\huge\mathfrak\red{Answer}$

The process in which an organism uses inorganic substances such as carbon dioxide, water and minerals to make its own food through another process called photosynthesis. The term photosynthesis was coined by Charles Ried Barnes in 1883.

Answer 2

Required Answer

Photosynthesis:

Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll, with oxygen as a by-product. Photosynthesis is an anabolic (building) process and is an important component of bioenergetics in living systems

It is the most important biochemical pathway and nearly all life depends on it.It comprises many Coordinated biochemical reactions that occur in plants, some protists (algae), and some bacteria. A simple general equation for photosynthesis is as follows:

$6CO_{2} + 12H_{2}O + \frac{ \sf{light}}{ \sf{energy}} \mid\frac{ \tt{light \: energy}}{ \longrightarrow \longrightarrow \longrightarrow} \mid C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O$

Phases of Photosynthesis:

There are two phases of photosynthesis

• light reaction

• Dark reaction

During first phase, light energy is capturedand is used to make high-energy molecules (ATP and NADPH). These eactions which are known as light reactions take place on the thyłakoid membranes of chloroplasts

During second phase, carbon dioxide is reduced to make glucose. In this phase the energy from high energy molecules (ATP and NADPH) is.utilized. Since these reactions.do not use light directly, they are known as dark reactions. The dark reactions take place in the stroma of the chloroplasts.
