Digestion & Enzymes Flashcards
What is the role of amylase?
Break down Starch into glucose
Where is amylase manufactured?
In the Pancreas, salivary glands and small intestine
What breaks down fats?
Lipase
Where is lipase manufactured?
In the Pancreas and small intestine
What is the role of protease
To break down proteins into amino acids
Where is protease manufactured?
In the stomach, pancreas and small intestine
What three ways is the small intestine adapted to absorb nutrients?
It is covered with villi, which give it a ‘curvy’ shape, and therefore a large surface area.
They have very thin walls, which create a small diffusion distance for the nutrients to diffuse through.
Have a rich blood supply, which enables it to absorb nutrients into the blood quicker and in a larger quantity.
What are two types of tissues found in the stomach and their roles?
Muscular tissue- contract and are used for movement
Glandular tissue- used to create hormones and enzymes
What is the role of isomerase in industry?
Used to convert glucose syrup to fructose syrup, which is put into ‘slimming’ foods and sports drinks, due to it having more sweetness at a lower amount (and lower amount of calories)
What is the role of lipase in industry?
Used in biological detergents to break down the fats in stains.
What converts starch to glucose syrup?
Amylase
What does raising the temperature do to the speed of reacting particles? What does this mean they do more of when colliding?
It increases it
They collide more Frequently and Energetically
What are two factors you can test on bio detergents?
Effect of pH and effect of temperature
What molecules are proteins digested to?
Amino acids
What makes an enzyme advisable?
it takes the least amount of time
