What else can I help you with?
How many times does the kreb cycle occur for each molecule of glucose consumed?
twice
Four of the five processes listed below degrade carbon compounds select the exception. A. Calvin-Benson cycle B. Kreb cycle C. Fermentation D. Respiration E. Glycolysis?
A. Calvin-Benson cycle is the exception as it is involved in carbon fixation during photosynthesis, while the other processes listed (Kreb cycle, fermentation, respiration, and glycolysis) are involved in degrading carbon compounds for energy production.
Where do the reactants for the Krebs cycle come from?
The reactants for the Krebs cycle come from the breakdown of carbohydrates, fats, and proteins into acetyl-CoA, which is then used as the starting molecule for the cycle. These molecules are broken down by various metabolic pathways in the cell to produce the necessary substrates for the Krebs cycle.
Does glycolosis or Krebs cycle come first?
Glycolysis evolved first. Cells of all types of organisms are able to carry out glycolysis. The Krebs cycle arose after photosynthetic organisms began adding oxygen to the atmosphere because Krebs cycle requires oxygen and glycolysis does not.
How many total phases are in cellular respiration?
3: Glycolysis, Kreb's, ETC
What follows glycolysis?
Kreb cycle.
What are the Stages of aerobic respiration?
The three stages are: Glycolysis, Kreb's cycle and Electron Transport
What is a product of aerobic respiration that will enter into and begin the Krebs cycle?
glycolysis yiels 2 pyruvate molecules that will undergo Kreb's cycle
What does kreb cycle make?
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.
What are the three stages of cellular respiration in order?
The three stages of cellular respiration in order are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Glycolysis takes place in the cytoplasm, the citric acid cycle occurs in the mitochondria, and oxidative phosphorylation takes place in the inner mitochondrial membrane.
What the respiration take place in the cell?
Glycolysis takes place in the cytoplasm. The Kreb's cycle and electron transport chain occur in the mitochondria.
What are the cycles of cellular respiration?
1. glycolysis 2. transition stage 3. the kreb cycle 4. the electron transport chain
How many times does the kreb cycle occur for each molecule of glucose consumed?
twice
What can you do with the end product of glycolysis?
The end product of glycolysis is pyruvate. Pyruvate can be further metabolized through aerobic respiration in the presence of oxygen, entering the citric acid cycle to generate more ATP. In the absence of oxygen, pyruvate can undergo fermentation to generate ATP anaerobically.

How are organic molecules such as glucose fatty acids and amino acids used by glycolysis and Kreb's cycle to produce usable energy?
Organic molecules like glucose, fatty acids, and amino acids are broken down through glycolysis and Kreb's cycle to produce usable energy in the form of ATP. In glycolysis, glucose is metabolized to produce pyruvate, which then enters the Kreb's cycle to generate high-energy molecules like NADH and FADH2. These molecules carry electrons to the electron transport chain, where ATP is generated through oxidative phosphorylation.
Where do the reactants for the Krebs cycle come from?
The reactants for the Krebs cycle come from the breakdown of carbohydrates, fats, and proteins into acetyl-CoA, which is then used as the starting molecule for the cycle. These molecules are broken down by various metabolic pathways in the cell to produce the necessary substrates for the Krebs cycle.
