Q. Why does cellular respiration have so many steps?
Cellular respiration uses oxygen in addition to glucose. It releases carbon dioxide and water as waste products. Cellular respiration actually “burns” glucose for energy. Instead, it releases the energy slowly, in many small steps.
Q. Why does respiration occur in steps and not all at once?
Why do the reactions of respiration occur step-by-step instead of all at once? If the reactions of respiration occurred all at once, the sudden release of heat energy would harm or destroy cells.
Q. Why is cellular respiration organized into four phases?
Why is cellular respiration organized into four phases? So that the energy within the glucose molecule can be released in a stepwise fashion.
Q. What are the two steps in cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Q. What is the most important stage of cellular respiration?
The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the …
Q. What organelle does aerobic cellular respiration in the presence of oxygen?
mitochondria
Q. What substances are used up as the reactants in cellular respiration 2 points?
Answer Expert Verified The cellular respiration happens in the mitochondria. During the cellular respiration, glucose and oxygen are the reactants during this process and the main product of this process is ATP, with waste products carbon dioxide and water.
Q. Which two activities provide the reactants for cellular respiration?
breathing in air and eating food.
Q. Which two activities provide the reactants for cellular respiration releasing air and exercising?
Breathing in air and eating food are the two activities which provide the reactants (oxygen and glucose) for cellular respiration.
