The products produced from contacting with the substrate and enzyme molecules must be removed continuously or else the rate of the reaction will slow. Enzyme activity is affected by temperature because chemical reactions increase as temperature increase. This is true of most enzyme reactions but once...
“Enzymes are proteins that have catalytic functions” [1], “that speed up or slow down reactions”[2], “indispensable to maintenance and activity of life”[1]. They are each very specific, and will only work when a particular substrate fits in their active site. An active site is “...
They serve as catalysts - speed up or slow down chemical reactions in the body Enzymes are make of ___. proteins How do enzymes catalyse reactions They lower the activation energy - they DONT increase amount of product, just the speed at which it is produced. What if an...
question 1 of 3 Enzymes are special proteins that ___ chemical reactions. Slow downDuplicate Speed upStabilize Worksheet PrintWorksheet 1. Salivary amylase is a type of ___ that helps break down carbohydrates that you eat. Substrate Enzyme ...
Explain how enzymes speed up chemical reactions. What is a factor that could speed up or slow down enzyme speed? What is an enzyme reaction? What are the characteristics of enzymes? (a) Describe how enzyme structure dictates enzyme function. (b) How can de...
The term used to describe all of the chemical reactions inside a cell ismetabolism(Figure 1). Cellular processes such as the building or breaking down of complex molecules occur through series of stepwise, interconnected chemical reactions calledmetabolic pathways. Reactions that are spontaneous and re...
Always favorable, downhill reaction 左图:Hydrolysis;右图:Condensation Reverse: Condensation reaction (右上图) Water is formed when chemical groups are joined - unfavorable Biological polymers made from condensation reactions: Sugar - polysaccharide(starch, glycogen) ...
Because of enzymes, cells can manage millions of chemical reactions per second, making our bodies efficient at creating energy from the raw materials we provide. Some of the key roles that enzymes play include: Digestion– Digestive enzymes help the body break down larger complex molecules into sm...
How do inhibitors slow down chemical reactions? How do enzymatic catalysts increase the rates of reactions? In a table format, explain the function and importance of enzymes. Do enzymes speed up chemical reactions? The graph shows the rate of product formation versus substrate co...
