Why do enzymes often require cofactors to facilitate activity? How does the concentration of enzymes affect enzyme activity? Describe the role of the digestive enzymes and the factors that affect their function. HINT: Think about the effect of enzymes on large macromolecules a...
THE procedures for the estimation of enzymes of the urea cycle reported by Brown and Cohen1 have made it possible to study quantitatively the effect of hormones on the individual reactions of the urea cycle. These authors have recently shown that, in rat
Enzymatic activity can be regulated by allostery. Explain how this influences the activity of enzymes in general. How do enzyme activators work? How does an enzyme perform catalytic activity with a substrate molecule? How does an enzyme help a reaction proceed?
The activities of enzymes in platelet activating factor (PAF) biosynthetic pathways were analyzed in hippocampal and cerebral cortical regions of normal and ischemic gerbil brain to assess changes in enzyme activities and potential modulators that could explain the accentuated production of PAF seen in ...
Due to the addition of these detergents, the enzyme activity in the soluble fraction was increased severalfold. Hydrophobicity of the enzyme was analyzed ... T Urbig,H Schiller,H Senger - 《Physiologia Plantarum》 被引量: 16发表: 1995年 Detergent compositions containing polycarboxylates and calciu...
The enzyme activity of histone deacetylase 8 is modulated by a redox-switch. Enzymes from the histone deacetylase (HDAC) family are highly regulated by different mechanisms. However, only very limited knowledge exists about the regu... Niklas,J?nsch,Christian,... - 《Redox Biology》 被引量:...
Enzymatic activity can be regulated by covalent modification. Explain how this influences the activity of enzymes in general. Define the term enzyme. Choose one enzyme and describe its function in the body. Enzymatic activity can ...
