The seventh reaction of glycolysis involves the conversion of ______ to?
1,3-bisphosphoglycerate . . . 3-phosphoglycerate
The sixth step of glycolysis results in the conversion of ______ to?
glyceraldehyde-3-phosphate . . . 1,3-bisphosphoglycerate
In which of these steps of glycolysis is ATP not produced nor is it hydrolyzed?
Glyceraldehyde-3-phosphate → 1,3-bisphosphoglycerate
In glycolysis, which of these reactions produce adenosine triphosphate (ATP)I. Conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerateII. Conversion of phosphoenolpyruvate to pyruvateIV. Conversion of 2-phosphoglycerate to phosphoenolpyruvate?
I and II
In this figure, the first intermediate, glyceraldehyde-3-phosphate, is converted into compound X. Following this, compound X is then converted into 3-phosphoglycerate. What is the identity of compound X?
1,3-bisphosphoglycerate
What is a bisphosphate?
A bisphosphoglycerate is any of a group of compounds containing two phosphoglycerate groups.
Why do blood banks dispose of blood with low levels of bisphosphoglycerate?
Blood with low levels of bisphosphoglycerate (BPG) may not deliver oxygen effectively to tissues when transfused into a patient. This can lead to inadequate oxygen supply, particularly in tissues with high oxygen demands like the brain and heart. Therefore, blood banks typically dispose of such blood to avoid potential complications in recipients.
Does glycolysis have steps involving oxidation-reduction reactions?
Yes, glycolysis involves several oxidation-reduction reactions. For example, the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate involves the oxidation of NAD+ to NADH. This process helps to generate energy in the form of ATP.
What is the net profit in ATPs of glycolysis?
The net production of ATP in glycolysis is 2 ATP molecules. This occurs through substrate-level phosphorylation during the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, and from phosphoenolpyruvate to pyruvate.
Which of the choices below is not a factor that promotes oxygen binding to and dissociation from hemoglobin?
Temperature is not a factor that directly promotes oxygen binding to and dissociation from hemoglobin. The main factors that influence this process are partial pressure of oxygen, pH, and the presence of other molecules such as carbon dioxide or 2,3-bisphosphoglycerate.
What happens when no NAD plus is present during glycolysis?
Without NAD+ in glycolysis, the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate cannot occur, halting the production of ATP. As a result, glycolysis is inhibited, and the cell's ability to generate energy through this pathway is compromised.
In which step of glycolysis is an inorganic phosphate added?
The addition of an inorganic phosphate molecule occurs during the first step of glycolysis, where glucose is phosphorylated to glucose-6-phosphate by the enzyme hexokinase or glucokinase.
