The most energetically favorable reactions in glycolysis are the phosphorylation of glucose to glucose-6-phosphate (catalyzed by hexokinase), the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate (catalyzed by phosphofructokinase), and the conversion of phosphoenolpyruvate to pyruvate (catalyzed by pyruvate kinase). These reactions are characterized by large negative changes in free energy, making them essentially irreversible under physiological conditions. They play crucial regulatory roles in the pathway, controlling the flow of metabolites through glycolysis.
What else can I help you with?
What c is where most of the chemical reactions occur?
Most chemical reactions occur in the cytoplasm of a cell, which is a gel-like substance that fills the interior space. The cytoplasm contains various organelles, enzymes, and substrates that facilitate biochemical processes. It is in this environment that metabolic reactions, such as glycolysis and protein synthesis, take place, allowing cells to function and respond to their surroundings.
Most of the reactions by which energy from sugars is released for use by the cell takes place within the?
Most of the reactions that release energy from sugars for cellular use occur within the mitochondria. This process primarily involves cellular respiration, where glucose is broken down through glycolysis, the Krebs cycle, and oxidative phosphorylation. These reactions convert the chemical energy stored in sugars into adenosine triphosphate (ATP), which cells use as a primary energy source.
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
Where the energy of glucose ends up?
After glycolysis, there is no more glucose. The name glycolysis means "sugar splitting," and that's just what it does. It takes one glucose and splits it into two molecules of pyruvate, generating two ATPs as it goes. Following the short reaction when entering the mitochondria, the acetyl CoA (a form of the pyruvate) goes through the Krebs Cycle (or Citric Acid Cycle). Through a series of reactions, the energy is taken and incorporated into ADP to make ATP. Some of the energy will also go to NAD+ to form NADH (and some to FAD+ to form FADH2). These electron carriers then go to the Electron Transport Chain (ETC) to make the most ATPs in respiration through oxidative phosphorylation.
In cellular respiration, what series of reactions break down glucose and produce atp?
Glycolysis is the first step in cellular respiration that breaks down glucose into pyruvate, generating some ATP. The Krebs cycle (or citric acid cycle) then further breaks down pyruvate to produce more ATP. Finally, oxidative phosphorylation in the mitochondria produces the most ATP through the electron transport chain.
What is the comparative and superlative degree of energetically?
Comparative: more energetically Superlative: most energetically
What is the adverb of energy?
The adverb most closely related to energy is "energetically," which means "in a vigorous or forceful manner." http://www.merriam-webster.com/thesaurus/energetically
In a cell most of the chemical reactions take place in the?
In a cell, most of the chemical reactions take place in the cytoplasm. The cytoplasm is a jelly-like substance that fills the cell and is where many metabolic pathways occur, such as glycolysis and protein synthesis. Additionally, organelles like the mitochondria and chloroplasts are specialized structures where specific reactions, like cellular respiration and photosynthesis, take place. Overall, the cytoplasm serves as the primary site for cellular activities and reactions to occur.

Glycolysis is thought to be one of the most ancient of metabolic processes Which statement supports this idea?
Glycolysis is the most widespread metabolic pathway.
What branch of chemistry is glycolysis?
Glycolysis is a metabolic pathway in the body, and is studied in most basic biochemistry classes.
How is glycolosis different from the breakdown of pyruvic acid?
Glycolysis is the breakdown of glucose to give pyruvic acid and energy. Pyruvic acid is then used for different reactions, the most important one being Kreb's cycle.
Why only glucose enters into glycolysis why not other sugars directly enter into glycolysis?
Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.
What is the most favourable position during intercourse to get pregnant?
vandals and spammers
What is the most favourable environment for a plant or an animal called?
Optimal environmental conditions
Who is the most famous member of tokio hotel?
The twins Tom and Bill seem to be the most favourable of the group.
