Flashcards in Elements Deck (13):
0

A major component of both organism and inorganic; as a gas essential to the oxidation of other foods fuels during which cellular energy (ATP) is produced

Oxygen

O

1

The primary element in all organic molecules including carbohydrates, lipids, proteins and nucleic acids

Carbon

C

2

A component of most organic molecules; as an ion (a changed atom) it influences the PH of the body fluids

Hydrogen

H

3

A component of proteins and nucleic acids (genetic material)

Nitrogen

N

4

Found as a salt in teeth and bones; in ionic form required for muscle contraction, neural transmission, and blood clotting

Calcium

CA

5

Present as a salt in combination with calcium in bones and teeth also present in nucleic acids and many proteins; forms part of the high energy compound ATP

Phosphorus

P

6

A compound of proteins (particularly contractile proteins of muscle)

Sulfur

S

7

As an ion the major extra cellular cation; important for water balance, a condition of nerve impulses and muscle contraction

Sodium

NA

8

An ionic form the most abundant ex cellular anion

Chloride

Cl

9

Present in bone; also an important cofactor for enzyme activity in a number of metabolic reactions

Magnesium

Mg

10

Needed to make functional thyroid hormones

Iodine

I

11

A component of the functional hemoglobin molecule (which transports oxygen within red blood cells) and more enzymes

Iron

Re

12

In its ionic form the major intercellular cation; necessary for the conduction of nerve impulses and for muscle contraction

Potassium

K
