To solve the question regarding the inhibition of the enzyme hexokinase by excess glucose 6-phosphate, we can follow these steps:Step 1: Understand the Role of Hexokinase Hexokinase is an enzyme that catalyzes the conversion of
Which enzyme is responsible for the splitting of ATP? The first step in glycolysis is catalyzed byhexokinase, 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-phosph...
Simple Summary Sex pheromone is an essential chemical signal for insect reproduction. Acetyl-CoA, which is generated from glycolysis, is the precursor of sex pheromone biosynthesis in Helicoverpa armigera. As the first speed-limited enzyme in glycolysis, the function of Hexokinase (HK...
Hexokinase, the initial and rate-limiting enzyme in the glycolysis pathway, is the site of action for the glycolysis inhibitor, 2-Deoxy-D-glucose (2-DG). This research demonstrated the effectiveness of 2-DG in reducing glycolysis and impairing mitochondrial function in cervical cancer cell lines ...
hexokinase1 (CzHXK1) as a master regulator of photosynthesis, carbon metabolism, and ketocarotenoid (astaxanthin) biosynthesis inC. zofingiensis. Thehxk1mutants are deficient in turning off photosynthesis and accumulating astaxanthin and lipids in the presence of glucose. HXK, a key enzyme in ...
NAG inhibition of hexokinase was of particular interest, because the enzyme (hexokinase I and/or II, depending on the cell type) associates with the mitochondrial outer membrane through an interaction with the voltage-dependent anion channel (VDAC). This interaction with the VDAC is involved in re...
pulex [11], and may serve as an explan- ation for the lower frequency of inter-host transfer in female L. salmonis [30, 31]. Although male-biased transcripts such as glycogen phosphorylase, fructose- bisphosphate aldolase, and hexokinase-2 enriched the GO category glucose metabolic process (...
Which enzyme is the key enzyme in glycogenolysis (glycogen degradation)? A. Phosphorylase B. Hexokinase C. Phosphoenol pyruvate carboxykinase D. HMG-CoA reductase E. Pyruvate kinase 你可能感兴趣的试题 单项选择题 Project scope can influence the time, quality and cost of the project. ( ) ...
We also identified an interaction between the HCV NS5A nonstructural protein and cellular hexokinase 2, the first rate-limiting enzyme of glycolysis. This interaction results in an enhancement of catalytic parameters of the enzyme, which might explain, at least in part, the aerobic glycolysis shift ...
aGlcN in its endogenously phosphorylated form, GlcN-6-phosphate, is a well-established inhibitor of both hexokinase4 (EC enzyme number 2.7.1.1) and, in particular, its predominant liver-specific functional isoform, glucokinase5 (EC 2.7.1.2), thereby reflecting the initial step within the ...
