Answer 1

The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm of the cell and needs no oxygen.

Glycolysis is the first stage of cellular respiration and doesn't require oxygen. In this stage, the enzyme split a molecule of glucose into 2 pyruvate molecules and this results in a nett gain of two ATP molecules.

The products of cellular respiration are--- E. carbon dioxide, water, and ATP

The second energy shell of an atom contains a maximum of D. Eight  the electron(s).

Each energy shell of an atom can contain a limited number of electrons. The first shell contains a maximum of 2 electrons. The second shell contains a maximum of 8 (2+6) electrons. The third shell contains a maximum of 18(2+6+10) electrons and so on.
