The three stages of cellular respiration are glycolysis, the krebs cycle, and electron transport

Electron transport.

Explanation: The cellular respiration takes through three important steps:

Glycolysis

Kreb's Cycle

Electron transport chain.

The process of cellular respiration can be defined as the process by which the glucose is broken down into high energy molecules which is used by the cells to perform metabolic activities.

In Glycolysis the glucose is broken down into pyruvate which combines which acetyl co A to enter in the Kreb's cycle which ends with the production of ATP moles at the last stage of cellular respiration, ETC.

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.
