Cellular respiration involves 3 steps:
1. Glycolysis, which occurs outside the mitochondria and also happens independent from cellular respiration.
2. The Krebs Cycle (or the Citric Acid Cycle) which occurs inside the mitochondria and involves stripping carbon from the molecules being catabolized in order to free up electrons.
3. The Electron Transport Chain, which uses oxygen (or sometimes another inorganic compound, but usually oxygen) to draw the freed electrons across a string of proteins, in the process moving hydrogen protons across a membrane internal to the mitochondria and then using these hydrogen protons to create ATP.

Two major stages of aerobic respiration?
The two major stages of aerobic respiration are the krebs cycle and electron transport.
Where in the cell do the two stages of respiration occur?
The first stage of cellular respiration, glycolysis, occurs in the cytoplasm. All subsequent stages occur in the mitochondria.
What are the two stages of respiration?
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
Are glucose and oxygen reactants in cellular respiration?
No ,it is not a by product.It is a reactant in respiration
What two substances are given off during respiration and used again during photosynthesis?
Glucose and oxygen are used up during respiration.
What happens in a mitochondria?
Aerobic respiration occurs in mitochondria, which produces ATP.
Two major stages of aerobic respiration?
The two major stages of aerobic respiration are the krebs cycle and electron transport.
What are the 3 stage of respiration?
The three stages of cellular respiration are glycolysis, Krebs cycle, and electron transport chain. During glycolysis glucose is split into two different molecules.
Where in the cell do the two stages of respiration occur?
The first stage of cellular respiration, glycolysis, occurs in the cytoplasm. All subsequent stages occur in the mitochondria.
compare two phases of photosynthesis?
Photosynthesis happens in two stages like light stage and dark stage while cell respiration happens in four stages called Glycolysis, Pyruvate Oxidation, Krebs cycle, and Electron Transport Chain. Carbon dioxide, Water, and Light energy are the main inputs of photosynthesis while cell respiration is Glucose and Oxygen
What are the two stages of respiration?
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
What stage of cellular respiration is gluclose broken down into two molecules of pyruvic acid?
This happens during glycolysis.
What two substances are given off during respiration and used again during photosynthesis?
Glucose and oxygen are used up during respiration.
Are glucose and oxygen reactants in cellular respiration?
No ,it is not a by product.It is a reactant in respiration
What are the two stages of cellular respiration?
Stage 1: Break down of glucose Stage 2: Production of ATP
What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
When you exhale what two stages of cellular respiration produce the carbon dioxide you are breathing out?
Preparatory Reaction and Citric Acid Cycle
