What happens during preparatory phase?
What happens during preparatory phase?
That refers to the development of the basic athletic attributes — speed, strength power, endurance, flexibility, balance, agility, and, ultimately, coordination. The preparatory phase develops these attributes by using the body’s reaction to specific types of exercise.
Is Calvin cycle part of cellular respiration?
The Calvin cycle is part of the light-independent reactions of photosynthesis. The Calvin cycle uses ATP and NADPH. The Krebs cycle is part of cellular respiration. This cycle makes ATP and NAPH.
What is preparatory phase in glycolysis?
The first five steps of Glycolysis are regarded as the preparatory (or investment) phase, since they consume energy to convert the glucose into two three-carbon sugar phosphates (G3P). The first step is phosphorylation of glucose by a family of enzymes called hexokinases to form glucose 6-phosphate (G6P).
What is the function of the preparatory phase of cellular respiration?
1. Preparatory phase: Energy in glucose cannot be readily released unless energy from ATP if added first. In this phase, 2 ATP are added to the reaction, producing a glucose molecule with two phosphate groups. The phosphate groups make glucose less stable and ready for chemical breakdown.
Why does cellular respiration occur?
Cellular respiration takes place (mainly) in the mitochondria because it is the cell’s “powerhouse”. It is where the energy (ATP) is produced in the cell, and the process of cellular respiration is the way the cells form that energy.
Where does respiration and cellular respiration occur?
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
What is the purpose of the preparatory phase in glycolysis?
The preparatory phase involves the conversion of glucose into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. This phase involves the investiture of energy equal to two ATP. This part of the glycolysis prepares glucose in the succeeding steps where ATP will be produced.
Which is the first phase of cellular respiration?
Glycolysis. Glycolysis is the first phase of cellular respiration and occurs outside the mitochondria while the other phases occur inside the mitochondria. Glycolysis come from the Greek words glyco which means sugar and lysis which means splitting.

Where are the carbons stored in cellular respiration?
Transition (preparatory) reaction Both pyruvates are oxidized and enter mitochondria Electron energy is stored in NADH Two carbons are released as CO 2 (one from each pyruvate) 8 Phases of Cellular Respiration
How many ATP molecules are produced during respiration?
The whole process of cellular respiration can produce a total of 36—38 ATP molecules per glucose molecule. For the glycolysis, 2 ATP molecules are produced plus two moles of NADH which when they enter the electron transport chain produces 4 or 6 ATP molecules.
