Question

The solar energy is converted into ATP in
A.Mitochondria
B.Chloroplast
C.Ribosome
D.Peroxisome

Answer 1

Hint:ATP is the standard energy currency of a cell. The ATP can be promptly integrated from ADP by a cycle, which is considered phosphorylation in which a phosphate is added to ADP.

Complete answer:
The cycle of photosynthesis in plants includes a progression of steps and reactions that utilizes sun based energy, water, and carbon dioxide to deliver certain compounds and oxygen. There are two primary arrangements of reactions: energy-transduction reactions (regularly called light responses) and carbon-fixation reactions (ordinarily called dark responses).

In the energy-transduction reactions, sunlight based energy is changed over into substance energy as two energy-shipping molecules, ATP and NADPH. At the point when sun powered energy arrives at plant cells and energizes unique chlorophyll particles, they discharge a high-energy electron. The arrival of this electron sets off a chain of electron-exchanging and energy-moving occasions between a few mediator atoms, and the last particle to frame and hold the electrons in this chain is NADPH.

The energized chlorophyll atom's electrons should be supplanted, and these electrons originate from water. With the assistance of catalysts and sun oriented energy, water is parted (photolysis) into electrons, protons (H+), and oxygen. The electrons go to the chlorophyll, while the protons add to a proton gradient that is utilized to control the amalgamation of a subsequent energy-conveying atom, ATP. The oxygen is a by-product of the entire cycle.

The compound energy in NADPH and ATP is then used to control steps in the further carbon fixation reactions.

Hence, the correct answer is option B.

Note:Phosphorylation in which a phosphate is added to ADP is completed by three techniques. They are oxidative phosphorylation, substrate level phosphorylation and photophosphorylation. At the point when phosphorylation happens in the presence of light in chloroplast, it is called photophosphorylation.
