How many ATP molecules are produced from one mole of glucose through complete metabolic process in bacteria?
32
Will starch ferment better than glucose?
It depends a little on yeast type, but they are both about the same. In the presence of one or the other, fermentation will take about the same time. In the presence of both, the glucose will be fermented first. Fructose and glucose are consumed by different metabolic pathways. When glucose is present the other pathways are suppressed.
Why is it important that metabolic pathways are regulated?
They can work via allosteric inhibition, where the final product in large amounts binds to a site (not the active site, but an allosteric site) which stops the enzymes involved in the early phases of the metabolic pathway. In other words, the final product can act as an inhibitor to stop the enzyme early in the metabolic pathway by deactivating it.
How do bacteria and viruses take in glucose as nutrition?
Bacteria take glucose through food or photosynthesis.Virus do not get glucose.
What metabolic reaction requires oxygen and glucose?
respiration
List five important features of glycolysis?
An early divergence in evolution has resulted in two prokaryotic domains, the Bacteria and the Archaea. Whereas the central metabolic routes of bacteria and eukaryotes are generally well-conserved, variant pathways have developed in Archaea involving several novel enzymes with a distinct control. A spectacular example of convergent evolution concerns the glucose-degrading pathways of saccharolytic archaea. The identification, characterization and comparison of the glycolytic enzymes of a variety of phylogenetic lineages have revealed a mosaic of canonical and novel enzymes in the archaeal variants of the Embden-Meyerhof and the Entner-Doudoroff pathways.
What are the metabolic pathways involved with making yogurt?
glycolytic pathway which explains the breakdown of glucose to pyruvate. the glucose is formed from initial breakdown of sucrose(sugar found in milk) to galactose and glucose. the pyruvate produced is then acted upon by lactic acid bacteria anaerobically to produce citric acid, hence the sour taste of yoghurt.

What is the advantage of using a metabolic pathway to burn glucose?
1. the energy is released gradually, which allows a significant amount of the released energy to be conserved for the cell to use rather than being lost as heat. 2. additionally, the process generates intermediate compounds into the metabolic pathways (divert surplus intermediate compounds into the metabolic pathways that best meet the organism's constantly changing needs)

Why are monosaccharides immediately phosphorylated upon entry into cells?
One example of modified monosaccharides are the phosphorylated sugars. An important phosphorylated sugar is glucose 6-phosphate, which is a glucose phosphorylated on carbon 6. The significance of this molecule is that it provides energy in certain metabolic pathways, and it can be converted and stored as glycogen when blood glucose levels are high. If blood glucose levels are low, glucose 6-phosphate can be converted back into glucose to enter the bloodstream once again. A unique property of glucose 6-phosphate is that once glucose is phosphorylated, the sugar possesses a negative charge. This prevents the molecule from leaving the lipid-bilayer membranes. This allows the cell to easily access the modified sugar to provide energy for metabolic pathways such as glycolysis, or convert it to glycogen as storage.
Which nutrient molecule is the pivotal fuel molecule in oxidative pathways?
glucose

How does the body breakdown carbohrydrates?
Carbohydrates such as glucose for example are catabolized(break down) by certain metabolic pathways. Glycolysis pathway is the first step where glucose is converted to pyruvate. Subsequently, pyruvate undergo Kreb's cycle and electron transport chain to synthesis energy or ATP molecules. Disaccharide (sucrose as example) or Polysaccharides such as Glycogen are first converted to its monomeric forms such as glucose, fructose, galactose etc. before entering the above said pathways.

What metabolic pathway generates 36 ATP from a single glucose molecule?
Glucose metabolism
