CHO
Definition
digestion: mouth, SI

Abosorbtion: SI
Term
Dig&Absortion

Pro

d: stomach, SI

Ab: SI
Term
Dig&Absortion

Fat
Definition

Term
Dig&Absortion

Vitamin & Mineral
Definition
D: freed

AB: SI & LI
Term
Dig&Absortion

Water
Definition
D: none

AB: stomach on, SI and LI
Term
Digestion
Definition
CHemical break down of food to nutrients
Term
Absorbtion
Definition
Transfer of nutrients into small intestine cell
-packaging of nutrients
-release into blood or lymph

-if body is low on nutrient, body will try to absorb more
Term
Enzymes
Definition
-Large protien molecules that facilitate specific chemical reactions
-high specificity:
Emzymes will only work on certain substances
-not altered by reactions
-names after substate: with 'ase'
Term
Digestion Enzymes

Substate: Protien
Definition
Enzyme: protease

Product: Amino acid
Term
Digestion Enzymes

substate: lipisd
Definition
Enzyme: Lipase

product: Fatty acid
Term
Digestion Enzymes

substate: amylose (CHO)
Definition
enzyme: amylase

product: sugars
Term
Digestion Enzymes

substate: lactose
Definition
Enzyme: lactase

product: glu & gal
Term
Four types of Tissues:
Definition
Epithehal-lines the outside surface and external passages - secretes, excretes, absorbs
Connective- supports and protects, holds structures together - stores fats, makes blood cells
Muscle- movement
Nervous- Transports nerve impulses
Term
Bile
Definition
Essential for fat digestion
-not an enzyme but an emulsifer
-made by liver, stored in gallbladder
-contains alot of cholesterol
-95% reabsored in small and large instestine
Term
Diffusion
Definition
Term
Facilitated diffusion/absorbtion
Definition
Term
Active transprort
Definition
Term
Phagocytosis/ Pinocytosis
Definition
Term
Carbohydrates
Definition
1st link in food chain
-photosynthesis: plants use 10% of suns energy to make CHO
-glucose is most abundant CHO
-Only significant animal source of CHO are milk + some milk products
Term
CHO Functions
Definition
-Energy: used in all cells
-Some cells (brain & RBC) can only use CHO
-Needed to effiently burn fat
-Spares protien from use for energy
-fiber, alternative forms of CHO provide a number of benefits
Term
CHO Differ by:
Definition
1. Type of building block (3 main ones)
2. Size (#of building blocks 1-1000s)
3. Type of chemical bond between biulding blocks
Term
CHO Termanology
Definition
Saccaride = building block
Simple CHO = 'sugars'
mono=1 di=2 tri=3
Complex CHO=starch/amylose, amylopectin
Complex CHO = fiber: different bonding then starches
Term
Monosaccharides
Definition
Glucose (Glu):most abundant CHO, part of table sugar,'blood sugar'
Fructose (Fru):found in fruit and honey, part of table sugar
Galactose (Gal):part of milk sugar, generally not found in nature
Term
Disaccharides
Definition
Sucrose= Glu + Fru - table sugar
Maltose= Glu + Glu- product of amylose digestion
Lactose= Glu + Gal- milk sugar
Term
Polysaccharides
Definition
Multiple glucose
-starch, amylose, amylopectin= many Glu
-Fiber= many different kinds, different chemical bonding then amylose- only found in plants
Glycogen- storage form of CHO in animals
Term
Major Hormones:
Definition
Insulin-
Glucagon-
Epinephrine
