Flauer [41]

Answer:

The correct answer is A. The statement is true.

Explanation:

Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.

Consider the diagram of a eukaryote and a prokaryote. According to cell theory,
Artemon [7]

both are single cells that carry out the functions of life

Explanation:

Both eukaryotic and prokaryotic cells are single cells according to the cell theory and they carry out the functions of life.

  • The cell theory postulates that all living organisms are made up of cells and that the cells are the basic organizational unit of life.
  • It also proposes that all cells arise from pre-existing cells.

Eukaryotic cells differs from prokaryotic cells in that they have true nucleus and membrane bound organelles.

Despite this seeming different, both cells are able to carryout different life functions as unit and when they combine together, they advance into higher organization of life.
