Main idea: glycolysis is needed for cellular respiration.
1. the function of glycolysis is to split
carrying molecules.
and produce energy-

Glycolysis is an organic catabolic process where small molecules are originated by splitting of a larger molecule.

Explanation:

A Catabolic reaction is a way by which we obtain any break down of a big organic matter into small parts.

Glycolysis is a great example of any catabolic reaction. Let see this process by the equation-

C6H12O6 (glucose) + 2 NAD+ + 2 ADP + 2 P > 2 pyruvic acid, (CH3(C=O) COOH + 2 ATP (energy) + 2 NADH + 2 H+

From the upper equation, we can see that it fracture the Glucose (energy carrier) and generates pyruvic acid (energy supplier) and ATP (energy) with some other byproducts, so we can easily say the primary function of Glycolysis is to produce energy by splitting one energy-carrying molecule.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day
