Digestive System Flashcards
What does Enzymes Mean
What are Enzymes
In yeast
These are substances made up of protein that speed up a biochemical reaction by modifying a specific substances called substrates.
What is digestion
Digestion breaks down food into its simplest so that the cells can use them
and the body on a whole
What are the two categories of enzyme
Intracellular- which Carries out it’s role in the cell it was made
Extracellular-Carries out its role outside the cell it was made
Eg Digestive Enzymes
Name 2 characteristic of Enzymes
What temperature does enzyme works best
Enzymes are made up of Protein
Enzymes are exact and work on specific substances and give specific byproducts
Enzyme are sensitive to temperature
37°C
What are digestive enzymes and some examples
These are enzymes produce by glands that secrete liquids that contain the enzyme
Salivary amylase
Proteases
Lipase
What do these enzyme act on:
amylase
Proteases
Lipases
Starch
Protein
Fats
How many molars, premolars, canine and incisors are in the adult body
8 incisors
4 canine
12 molar
8 premolar
What is secreted from the salivary?
What enzyme does this contain
Saliva
Salivary amylase
What is secreted form the Gastric gland in the stomach wall
Gastric juice with the enzyme pepsin and rennin
What secretes pancreatic juice?
Pancreas
What enzymes are in pancreatic juice, what do they act on and produce
Lipase-fats=glycerol and fatty acids
Pancreatic amylase-starch=maltose
Trypsin-protein=amino acids
Intestinal juice gives what enzymes and what do they work on and produce
Polypeptides-proteins=amino acids
Sucrase-sucrose=galactose and glucose
Maltese-maltose=glucose
Lactase-lactose=glucose and galactose
Lipase-fats= fatty acids and glycerol
The teeth consist of how many minor part
Two
Crown
Root
The crown has 3 structures name them
The Dentine
Enamel
Pulp cavity
The enamel is……
Hardest substances in the body, it’s non living, resistant to chipping and decay
It’s protects the tooth
