Question

please help me (make sure the answers are correct please)

One of the most important steps in the evolution of life on Earth was the appearance of certain organisms in which photosynthesis takes place. Why was this critical? A population of a Bacillus species is growing in a soil sample. Suppose glycolysis came to a halt in these bacterial cells. Would this mean that the citric acid cycle would also stop? Why or why not?

Answer 1

(2) Earliest organisms that lived on earth were heterotrophs which depend on the organic molecules for food and oxygen them, autotrophs evolved which are capable of convealing the inorganic molecules into 049amie molecules and food for the heterotroph's. Aequiring the machinery of pholosynthesis gave the early organisms a huge evolutionary advantage. Photosynthetic cyanobacteria reengineered the planet. photosünthesis lead to two more singularities - plants and animals - Photosynthesis permits ja lange planetary biomass on Earth. . Oxygenic photosynthesis has allowed am oxygenated atmosphere and evolution of Large metabolically demanding creature , including us.. (3) citric acid cycle won't halt in the bacterial il cell, when glycolysis stop. Glycolysis provide pyourate and this is converted to ncereyl-con that enters citric acid cycle. But bacterial cell can get acetyl-CoA by beta- oxidation, a catabolic process by which farley acid molecules are broken down in the eynosol in prokaryotes to generate acetyl-CoA. This can muloim eitric acid cycle'. enter
