What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What tells the story of a chemical reaction?
The balanced chemical equation for a reaction tells the story of a chemical reaction by showing the reactants that are consumed and the products that are formed. It also provides information on the stoichiometry of the reaction, including the ratios of reactants and products involved.
Define chemical reaction and chemical equation?
A chemical reaction is a process that results in the transformation of chemical substances into new substances with different properties. A chemical equation represents this reaction using chemical formulas of the reactants and products, along with their respective coefficients to balance the equation.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What is the rate of the pepsin-catalyzed reaction at pH 8 with the rate of the lipase-catalyzed reaction at pH 8?
The rate of the pepsin-catalyzed reaction at pH 8 is generally low because pepsin is most active in the acidic environment of the stomach, typically around pH 1.5 to 3.5. In contrast, lipase operates optimally at a higher pH, around pH 7 to 8, making it more effective under those conditions. Therefore, at pH 8, the lipase-catalyzed reaction would likely proceed at a significantly higher rate than the pepsin-catalyzed reaction.
Which enzyme works best in alkaline conditions?
Pepsin in the stomach
Lipase are to lipids as pepsin is to?
pepsin is used to degrade food proteins to peptides.
Is effect of pepsin on proteins a chemical reaction?
Yes, it is. Proteins in the presence of pepsin are converted into peptide chains (polypeptides). The reaction is : Proetins→ (In the presence of pepsin-to be written over the arrow) Polypeptides.
Why arn't lipase and amylase secreted into the stomach with pepsin?
Lipase and amylase require an alkaline environment such as what is found in the duodenum of the small intestine. Pepsin functions in the acidic environment of the stomach.
What is digestiv hormone a- lipase b-pepsin c- amylase d- gastrin?
Lypase,Pepsin and Amylase are enzymes.Gastrin is a hormone.
What are some examples of proteinsz?
1-keratin 2-renin 3-pepsin 4-pencreatin 5-panceatin lipase 1-keratin 2-renin 3-pepsin 4-pencreatin 5-panceatin lipase
Where are lipids first digested?
by bile in the stomach then by lipase by bile in the stomach then by lipase
What is the reaction for pepsin?
it is the
What is the role of amylase pepsin and lipase in the digestionof food?
Amylase, pepsin, and lipase are enzymes that play crucial roles in the digestion of food. Amylase, found in saliva and the pancreas, breaks down carbohydrates into simpler sugars. Pepsin, active in the acidic environment of the stomach, digests proteins into smaller peptides. Lipase, primarily produced by the pancreas, is responsible for breaking down fats into fatty acids and glycerol, facilitating their absorption in the intestines.
What is the balanced chemical equation for lipase?
Lipase is NOT a specific biochemical reaction. It is an enzyme catalyzing the enzymatic breakdown (hydrolysis) of fats (lipids). triglyceride (fat) + water --> 3 fatty acids + glycerol
What are some enzymes found in the digestive system?
Pancreatic amylase Lipase Pepsin Salivary amylase Maltase Rennin (younger version of pepsin mostly found in babies)
