Chapter 7, Problem 1TY

The water necessary for photosynthesis

is split into H₂ and O₂.
is directly involved in the synthesis of carbohydrates.
provides the elections to replace lost electrons in photosystem II.
provides H⁺ needed to synthesize G3P.
does none of the above.

Expert Solution & Answer

Summary Introduction

Introduction:

The Calvin cycle utilizes the energy produced by the light-dependent reaction into synthesizing carbohydrates from carbon dioxide. The NADPH (nicotinamide adenine dinucleotide phosphate) acts as a reducing agent that adds the high energy electrons to the carbon dioxide molecule to form polysaccharide (glucose).

Answer to Problem 1TY

The correct answer is option (c) provides the electrons to replace lost electrons in photosystem II.

Explanation of Solution

Explanation/justification for the correct answer:

Option (c) provides the electrons to replace lost electrons in photosystem. Water does provide lost electrons for photosystem II that are used for the electron transport chain. So, the correct answer is option (c).

Explanation for incorrect answer:

Option (a) is split into H₂ and O₂. Splitting of water under the presence of light to yield hydrogen and oxygen is known as photolysis of water to provide electrons for the reaction. So, this is an incorrect option.

Option (b) is directly involved in the synthesis of carbohydrates. Water is no directly involved in the synthesis of carbohydrates as it provides electrons for reduction of NADH that participates in the production of carbohydrates. So, this is an incorrect option.

Option (d) provides H+ needed to synthesize G3P. The protons for the synthesis for G3P come from the photolysis of water, but that is not the necessary source of protons they can also come from thylakoid membrane. So, this is an incorrect answer.

Option (e) does none of the above. The water is necessary for the compensation of the electrons that are lost in the photosystem II and these electrons participate in the electron transport chain. So, this is an incorrect answer.

Conclusion

Water is required as a source of electrons in the light reaction where photosystems get activated and lead to an electron transport chain to produce energy-rich molecules. Hence, the correct answer is option (c) provides the electrons to replace lost electrons in photosystem II.
