WHAT ARE THE RISKS OF EATING TOO MUCH PR0TEIN?
Definition

-HIGH COLESTEROL

-HEART DISEASE

-POSSIBLE BONE LOSS

-KIDNEY DISEASE 

Term
MARASMUS

Term
PHENYLKETONURIA (PKU)
Definition
INHERITED DISEASE WHERE THE INDIVIDUAL CANNOT BREAK DOWN THE PROTEIN PHENYLALANINE. CAN CAUSE BRAIN DAMAGE
Term
CYSTIC FIBROSIS

Definition
SUCROSE
Term
WHERE DOES GLUCOSE COME FROM?
Definition
PLANTS. IT IS THE MOST ABUNDANT SOURCE OF CARBOHYDRATES
Term
SIMPLE CARBOHYDRATE
Definition
COMMONLY REFFERED TO AS 'SUGARS'. CONTAIN ONE OR TWO MOLECULES, RESPECTIVELY CALLED MONOSACHARRIDES AND DISACHARRIDES
Term
COMPLEX CARBOHYDRATE
Definition
LONG CHAINS OF GLUCOSE MOLECULES. INCLUDES STARCH, GLYCOGEN, FIBER. POLYSACHARRIDES
Term
STARCH
Definition
STORAGE FORM OF GLUCOSE IN PLANTS
Term
GLYCOGEN
Definition
STORAGE FORM OF GLUCOSE IN ANIMALS
Term
FIBER
Definition
FORMS SUPPORT STRUCTURES IN PLANTS. LEAVES STEMS, ETC.
Term

Term
SOLUABLE FIBER
Definition
COMES FROM THE INSIDE AND AROUND THE OUTSIDE OF A PLANT'S CELLS; DELAYS STOMACH EMPTYING; SLOWS THE ABSORBTION OF GLUCOSE; FERMENTATION OF SOLUABLE FIBER IN THE LARGE INTESTINE HAS MANY BENEFITS
Term
INSOLUABLE FIBER
Definition
COMES FROM THE PLANT'S CELL WALLS; INCREASES FECAL BULK BY ABSORING MORE WATER; SOFTENS STOOL; SPEEDS UP FECAL TRANSIT TIME.

Term
MALTASE, SUCRASE, LACTASE
Definition
ALL ENZYMES PRODUCED BY THE PANCREAS AND RELEASED INTO THE SMALL INTESTINE TO AID IN THE DIGESTION OF THEIR RESPECTIVE CARBOHYDRATE.
Term
WHAT IS THE BODY'S PRIMARY ENERGY SOURCE?
Definition
GLUCOSE IN THE BLOOD.
Term
WHAT HAPPENS TO THE EXCESS GLUCOSE IN THE BODY?
Definition
IT IS STORED AS GLYCOGEN IN THE LIVER AND MUSCLES.
Term
HOW IS GLUCOSE REGULATED IN THE BLOOD?
Definition
A BALANCE OF A RELEASE OF INSULIN AND GLUCOGON FROM THE PANCREAS
Term
INSULIN
Definition
PRODUCED BY THE BETA-CELLS OF THE PANCREAS. HELPS IN THE ABSORBTION OF GLUCOSE. STIMULATES THE LIVER TO TAKE UP GLUCOSE AND CONVERT IT TO GLYCOGEN.
Term
GLUCOGON
Definition
PRODUCED BY THE ALPHA-CELLS OF THE PANCREAS. BREAKS DOWN GLYCOGEN TO GLUCOSE TO MAKE GLUCOSE MORE ABUNDANT TO THE SOMATIC CELLS.
