Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells
Explanation:
Totipotent (or Omnipotent) Stem Cells.
Pluripotent Stem Cells.
Multipotent Stem Cells.
Oligopotent Stem Cells.
Unipotent Stem Cells.
The DIRECT PHOSPORYLATION OF ADP BY CREATINE PHOSPHATE is the most inefficient pathway to regenerate atp during 30 minutes of light to moderate exercise.
Aerobic respiration is the pathway for regenerating atp that provides the majority of the energy used for muscle activities during 30 minutes of light to moderate exercises.
