Electron | MCQs

Explanation

During light reactions, PS II receives electrons from the splitting of water.

This process, known as photolysis, generates oxygen, protons, and electrons.

It replenishing the electron supply in Photosystem II.

Explanation

Enzyme NADP reductase is responsible for reducing NADP⁺.

It catalyzes the transfer of electrons to NADP⁺, forming NADPH, which is used in the Calvin cycle for carbon fixation.

Explanation

In the journey of electrons from photosystem II to photosystem I, plastocyanin is reduced by the cytochrome complex.

The cytochrome complex facilitates the transfer of electrons to plastocyanin, which then carries them to Photosystem I.

Explanation

computer chip, also called chip, integrated circuit or small wafer of semiconductor material embedded with integrated circuitry.

Chips comprise the processing and memory units of the modern digital computer.

Explanation

Very large-scale integration is the process of creating an integrated circuit by combining millions of MOS transistors onto a single chip.

Explanation

Because black gives consonant sound 

Explanation

The term RADAR was coined in 1940 by the United States Navy

It is an acronym for "radio detection and ranging".

It is a radiodetermination method  used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
