What key reactant is needed to drive cellular respiration

Glucose and Oxygen are the key reactant that is needed to drive cellular respiration. Respiration is a energy releasing process in which energy is released due to the breakdown of glucose molecules with the help of oxygen which produces carbondioxide, water and energy in the form of Adenine tri phosphate (ATP). Carbondioxode is a waste product which is removed from the cell and ATP is used by the cell for performing different functions.

d. groundwater flows through the subsoil and deposits minerals.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
