What are enzymes easy answer?
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
What are some questions about enzymes?
Enzymes – Edexcel test questions – Edexcel
- What affect does extremely high pH have on enzymes?
- What does the term optimum mean for enzyme temperature?
- What type of enzymes break down carbohydrates?
- What type of enzymes break down fats?
- What type of enzymes break down proteins?
- What type of enzyme is amylase?
What was the purpose of the enzymes lab?
The purpose of this lab is to investigate the impact of temperature, substrate concentration, enzyme concentration, and the presence of an inhibitor on the effectiveness and rate of an enzyme. If the concentration of the enzyme or substrate is increased, the rate of the reaction will be increased as well.
What are examples of enzymes?
Examples of specific enzymes
- Lipases – a group of enzymes that help digest fats in the gut.
- Amylase – helps change starches into sugars.
- Maltase – also found in saliva; breaks the sugar maltose into glucose.
- Trypsin – found in the small intestine, breaks proteins down into amino acids.
How do you measure enzyme activity in a lab?
Enzyme assay
- Enzyme assays are laboratory methods for measuring enzymatic activity.
- The quantity or concentration of an enzyme can be expressed in molar amounts, as with any other chemical, or in terms of activity in enzyme units.
- Enzyme activity = moles of substrate converted per unit time = rate × reaction volume.
What are 5 properties of enzymes?
The properties of an enzyme can be summarized as:
- (1). Catalytic Property.
- (2). Specificity.
- (4). Sensitiveness to Heat and Temperature.
- (5). Specific to Hydrogen Ion Concentration (pH)
How could you test to see if an enzyme was completely saturated?
How could you test to see if an enzyme was completely saturated during an experiment? (2 pts) To test this, you’d simply see if the reaction was still taking place. If the enzyme was completely depleted, the reaction could no longer occur.
What are 3 things that can affect enzyme activity?
Be specific with your explanation. (2 pts) Temperature, salinity, and acidity are three conditions that affect enzyme activity. Specific examples include: Adding a salt packet to an enzyme would alter its activity–salt ions are often necessary for optimal enzyme activity, so too much or too little salt will slow down the rate.
How do you identify household products that work by enzymes?
Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme. (2 pts) Some examples include: contact lens cleaner (protease), dish soap (amylase), cheese
What can slow down the rate of enzyme activity?
Higher or lower pH than the optimum slows the rate of activity. 3. Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme. (2 pts)
