The most basic concepts of cell theory are that cells are the basic units of life and that all living things are made of cells. which answer correctly explains why these concepts are the basis of a theory and not a hypothesis? cell theory explains how cells function rather than predicting how they function. cell theory has been unchanged for many decades and as a result can be accepted as fact. cell theory is a prediction based on observation and not a fully accepted idea. cell theory remains largely untested rather than being subject to testing.

Answer : Option B) Cell theory has been unchanged for many decades and as a result can be accepted as fact.

Explanation : As cells are basic units of life and all the living beings are made up of cells, this was correctly defined by the cell theory. This theory is since its discovery not changed for many decades and is widely accepted as a fact too.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
