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 are simple sugars known as?
They are sugars that the body can use directly, unlike complex sugars which the body has to first break down. Glucose is an example.
What is fructose and glucose examples of?
Sugars.
What are glucose fructose and ribose examples of?
Sugars.
What Produces 3 carbon sugars?
Mainly falsely assume it creates glucose, but it makes 3C sugars as you indicated like PGAL which can be used in the the production of glucose.
Monomer of Carbohydrates?
monosaccharides which are single simple sugars( glucose, fructose galactose)
What simple sugars starts glycolysis?
glucose
Glycolysis is a process found in?
Answer D - the initial breakdown of glucose to pyruvic acid
What statement describes what happens with ATP during glycolysis?
More ATP is produced than is used.
How is glucose changed as it moves through glycolysis?
Glucose is modified by particular reactions, and eventually splits into 2 3 carbon sugars, which interconvert between each other. These are modified further to produce pyruvate. Glycolysis literally means, "splitting sugars".
What is the difference between glycolysis and gluconeogenesis?
Glycolysis is the breakdown of glucose into pyruvate, generating ATP and NADH, while gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors such as amino acids, lactate, or glycerol. Glycolysis is a catabolic process, whereas gluconeogenesis is an anabolic process that occurs mainly in the liver and kidneys to maintain blood glucose levels during fasting or low carbohydrate intake.
An anaerobic metabolic pathway that results in the production of two net ATP per glucose plus two pyruvic acid molecules is?
Glycolysis is an ATP-generating metabolism that takes place in almost all living cells. It refers to the process of breaking down glucose or other sugars and converting them into pyruvic acid.
What happen to ATP during glycolysis?
During glycolysis, more ATP is produced than is used Glycolysis - occurs in the cytosol begins the degradation process by breaking glucose into two molecules of pyruvate. Glucose is a six carbon sugar, and it becomes split up into two three carbon sugars. Glycolysis has two phases, energy investment and energy payoff. In order to begin glycolysis, the cell must spend two ATP molecules. Directly from glycolysis, 4 ATP are made. Once the cell is paid back for its loss of two ATP's, the net gain of glycolysis can be said to be 2 ATP. Along with making ATP, the cell also makes 2 NADH

How is glucose catabolized?
pancreas since it is sugar _______ The pancreas doest not break down glucose. Digestion of sugars start at the mouth where salivary amylase begins to act on starch. The digestion of the rest of the sugars occurs in the duodenum of the small intestine. The result of digestion is a mass of simple sugars like glucose. Then on the cellular level, glucose is first broken down in the cytoplasm via glycolysis. The products are then directed to the inter-membrane space where the Krebs Cycle occurs. Finally, the electron transport chain within the mitochondria will deliver the highest output of ATP using the products of both glycolysis and the Krebs Cycle. So in short, glucose is actually broken down in the cytoplasm of the cell.
Why Hexokinase phosphorylated the glucose at first step of glycolysis?
The first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.
Are glucose and fructose reduced sugars?
Glucose and fructose are reducing sugars.
Which best explains how human body obtains energy from food?
Typically glycolysis. Glycolysis is a process by which sugars (specifically glucose) is broken down into ATP (energy). There are, however, many pathways to derive energy from differently moleculs (including lipids and carbohydrates).
