Put these steps of the citric acid cycle into the correct sequence. 1. The breakdown of one glucose molecule produces two acetyl
Tpy6a [65]

Answer:

The correct sequence of steps in citric acid cycle has been mentioned below -

Explanation:

  • 2 acetyl CoA molecules are produced from the breakdown of one glucose molecule.
  • Acetyl CoA combines with oxaloacetate to form citrate and releases CoA.
  • Two carbon atoms are released from acetyl CoA and combine with oxygen to form carbon dioxide.

The sequence of steps is correct in the question i.e. 1 → 2 → 3

These are the first three steps in the citric acid cycle which occurs during the cellular respiration.

Put the following steps of dna replication in chronological order. 1. Single-stranded binding proteins attach to dna strands. 2.
uranmaximum [27]

The correct order is:

2. Hydrogen bonds between base pairs of antiparallel strands are broken  

Enzymes called helicases are responsible for this process because their role is to separate two DNA strands so they can be replicated.

1. Single-stranded binding proteins attach to DNA strands.  

After two strands are separated into a Y shape-replication fork single strands are free for the replication machinery. Single strands are the templates for replication to begin.

3. Primase binds to the site of origin.  

Primase is an enzyme which functions as RNA polymerase and thus catalyzes the synthesis of a short RNA segment-RNA primer.

5. An RNA primer is created.

Primer RNA is short RNA sequence that initiates DNA synthesis because DNA polymerase is disable to initiate polynucleotide synthesis by itself.  

4. DNA polymerase binds to the template strand.

DNA polymerase binds to the strand at the site of the primer. The function of this enzyme is to add new nucleotides complementary to other strand.
