Cellular respiration definition ?

cellular Respiration is that cells use oxygen in mitochondria to make ATP and GTP for cells

Cellular respiration occurs when cells utilize oxygen in their mitochondria to produce ATP and GTP.

Cellular respiration is a series of reactions that occur under aerobic conditions and result in the production of large amounts of ATP.

Explanation:

Glucose, the basic building block for starch and many sugars are one of the main sources of energy in our diet. Its oxidation can be divided into three phases in the respiration of the cells: glycolysis, the cancer cycle, and the electron transport system.

Aerobic breathing uses eukaryotes to generate energy, including all multicellular organisms and some single-cell organisms. Aerobic breathing uses oxygen – a powerful, in-kind electron acceptor.

Aerobic breathing is an extraordinarily effective process that enables eukaryotes to have complicated life and active lifestyles. It also means however that they need a continuous supply of oxygen or that they cannot get the energy to stay alive.

Other forms of respiration, which are slightly less efficient, can be used by procharian organizations such as bacteria and archaebacteria. They can therefore live in environments in which eukaryotic organisms cannot live because they do not need oxygen.

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.
