What is produced in Stage 1 of respiration?
Stage one. Glucose in the cytoplasm of cells is broken down into two molecules of pyruvate . This releases enough energy to produce two molecules of ATP for every molecule of glucose that is broken down.
What is the second stage of respiration?
The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2.
What is the second stage of cellular respiration?
The second stage of cellular respiration, called the Krebs cycle , takes place in the matrix of a mitochondrion.
What two stages does cellular respiration occur?
Stages of Cellular Respiration Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen.
What process occurs in the first stage of cellular respiration?
Glycolysis is the first stage of cellular respiration that involves the breaking down of glucose into smaller molecules to produce ATP (cellular energy). Glycolysis occurs in the cytosol of all living organisms.
What are the 7 steps of cellular respiration?
The steps of aerobic cellular respiration are: Glycolysis (the break down of glucose) Link reaction Krebs cycle Electron transport chain, or ETC
What are the four phases of cellular respiration?
The four different phases of the cellular respiration process are: glycolysis, pyruvate oxidation, the citric acid cycle or Krebs cycle, and oxidative phosphorylation. Phases of cellular respiration detailed: Glycolysis , citric acid/Krebs cycle, electron transport chain.
What stage in cellular respiration produces the most energy?
Oxidative phosphorylation is by far the most productive stage of respiration. Far more usable cellular energy is produced during oxidative phosphorylation than during glycolysis and the citric acid cycle combined. Oxidative phosphorylation includes two phases: the electron transport chain and chemiosmosis .
