ATP because its essentially stored energy. All the cell has to do to release the energy is break off a phosphate. ATP is like money in the bank. It's there when cells need energy. Glucose is the preferred molecule to go through the krebs cycle to be made into ATP, but it has to be converted to ATP before its energy can be used. Starch is a macromolecule and has to be broken down into monosaccharides and then converted into ATP, so it's not he most direct source of energy. DNA is the code for telling the cells what proteins to make. It's not a source of energy.  Sorry its long but hope it helps!!

BigorU [14]

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

Answer:

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

Ksenya-84 [330]

If a plant cell had a mutation such that the cyclic electron flow is observed at a much higher rate, which photosystem is most likely mutated such that energy is absorbed at a lower rate?

PSI

PSII

Answer:

PSII

Explanation:

Non-cyclic phosphorylation involves both PSI and PSII. The process starts with the splitting of water and excitation of electrons of the reaction center of PSII upon the absorption of solar energy at the wavelength of 680 nm. Any mutation in PSII would not allow the non-cyclic phosphorylation to occur when only cyclic phosphorylation would occur. The process of cyclic phosphorylation includes only PS I. Its reaction center absorbs maximum light at 700 nm and is cycled back while supporting ATP synthesis. Therefore, if a plant performs cyclic phosphorylation at a higher rate and absorbs less energy, this means that mutation was in PSII.
