What is required for both the light-dependent and light-independent reactions to proceed? energy co2 water atp and nadph

Option A, Energy

Explanation:

Energy is required for driving both the processes i.e light dependent reaction and light independent reaction

In the light dependent reaction , energy in the form of solar energy is used to produce food and energy molecules such as Adenosine Tri Phosphate (ATP) and nicotinamide adenine dinucleotide phosphate hydrogen (NADPH). These two molecules are known as energy molecules and act as a source of energy for light independent reaction taking place in dark.

Hence, option A is correct

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
