Question

Which of these processes is a nearly universal energy-releasing metabolic process that indicates common ancestry for all life on earth?

A) Glycolysis
B) Photosynthesis
C) Chemosynthesis
D) Cellular Respiration

Answer 1

A) Glycolysis

Step-by-step explanation:

Glycolysis Glycolysis is anaerobic, so no oxygen is required. It occurs in the cytoplasm, so no organelles are involved. It produces more ATP than is consumed, so it is energy-releasing. Therefor, all cells on earth can perform glycolysis. Other energy harnessing and releasing processes (photosynthesis, chemosynthesis, and aerobic cellular respiration) are only performed by certain cell types.

Answer 2

Which of these processes is a nearly universal energy-releasing metabolic process that indicates common ancestry for all life on earth?

The answer is option A) Glycolysis

Glycolysis is the process in which glucose is broken down by enzymes, thus releasing energy and pyruvic acid. All cells can perform anaerobic respiration by glycolysis.
