What are the products of the light reactions of photosynthesis that are utilized in the calvin cycle?
suter [353]

Answer:

The correct answer is ATP and NADPH

Explanation:

During the light reaction, the light energy is absorbed by the chlorophyll pigment present in the thylakoid membrane which moves through different electron acceptors and allows the formation of NADPH and ATP.

This ATP and NADPH get utilized into the Calvin cycle during carbon fixation, reduction and regeneration steps. This utilization converts ATP and NADPH into ADP and NADP+. The energy released by them is used to fix carbon to produce organic compounds. Therefore the correct answer is ATP and NADPH.

What are the 3 different shapes, or structures, or carbon base molecules?
ddd [48]

Answer:

Carbon based molecules have 3 main structures which are

straight chain

branched chains

rings

Explanation:

The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.
