Which of the following statements accurately describes the function of a metabolic pathway involved in cellular respiration? a. the function of the citric acid cycle is the transfer of electrons from pyruvate to nadh to o2b. the function of the bonding of acetic acid to the carrier molecule coa to form acetyl coa is the reduction of glucose to acetyl coac. the function of glycolysis is the begin catabolism by breaking glucose into two molecules of pyruvate, with a net yield of two atp

The function of glycolysis is to begin catabolism by breaking glucose into two molecules of pyruvate, with a net yield of two ATP

Explanation:

Glycolysis is the very first step of cellular respiration. It breaks down glucose into two molecules of pyruvate. During glycolysis, 2 molecules of ATP and 2 molecules of NADH are formed. Pyruvate enters the TCA cycle in the form of acetyl CoA.  

The NADH formed in glycolysis and TCA cycle enter oxidative phosphorylation to drive ATP synthesis.  

Hence, glycolysis serves to start the process of cellular respiration.  

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
