What are the reactants for cellular respiration? (1 point)

In cellular respiration oxygen and glucose are both reactants. Cellular respiration is mostly based on ATP; carbon dioxide and water from waste products.

Explanation:

Glucose and oxygen are reactive to ATP in cellular breathing. The by-products are water and carbon dioxide. Glycolysis (anaerobic process), a cancer cycle, and oxidative phosphorylation are three steps of aerobic cell breathing.

CO2 + Oxygen CO2 + H 2O C6H12O6 + 6O2 +Water Glucose (sugar), Sugar Cellular breathing, or aerobic breathing is a sequence of chemical processes which, in the presence of oxygen, start with sugar reactants and create carbon dioxide and water as waste products.

thymine. in rna, thymine is replace by uracil

i think its the first one
