Chemicals in Organisms Flashcards
Matter
anything that occupies space and has mass
Mass
quantity of matter in any body
Weight
the gravitational attraction exerted by a large body of matter on an object
2 Pure Substances
- Elements
- Compounds
Pure Substance
have fixed chemical composition and its elemental constituents does not change when subjected to different processes
Elements
made up of only one kind of atom and has the simplest chemical forms
Kinds of Matter
- Pure Substance
- Mixture
difference between organic and inorganic compounds
organic compounds always have a carbon atom, while most of the inorganic compounds do not contain a carbon atom in them
Mixture
made up of two or more different substances mixed but not combined chemically
Physical Properties
properties of matter which can be observed without changing the substance into some new kind of matter
Chemical Properties
properties that can be observed only when the substance undergoes a change in composition; determine the ability of a substance to react with other substance
boiling point
100°C
freezing point
0°C
Density
compactness of a substance; more compact, more dense
Gases
substances that neither have definite shape nor definite volume
Liquids
substances that have definite volume but no definite shape
Solids
materials that have definite shape and volume
Plasma
a mixture of sub-atomic particles of nuclei and electrons
4 Physical States of Matter
- Gases
- Liquids
- Solids
- Plasma
4 Energy storing Molecules
- ATP – ADENOSINE TRIPHOSPHATE
- ADP – ADENOSINE DIPHOSPHATE
- FADH2 – FLAVINE ADENINE NUCLEOTIDE
- NADH – NICOTINAMIDE ADENINE
DINUCLEOTIDE
Nucleus
the tiny central part of an atom that contains the protons and neutrons
3 Sub-atomic Particles
- Protons
- Neutrons
- Electrons
Protons
positively charged particles of an atom
Atom
the smallest particle of an element that has the properties of that element; basic building block of matter; made of smaller particles protons, neutrons, and electrons
Neutrons
neutral particles of an atom located in the nucleus of the atom
Electrons
the negatively charged particles of an atom that are found outside and revolving around the nucleus
Electrons
the negatively charged particles of an atom that are found outside and revolving around the nucleus
Ions
the most stable, or unlikely to react when its outermost energy level is completely filled
atom that has lost or gained electrons
ion
Isotopes
atoms of the same element that have different numbers of neutrons
Atomic Number
the number of protons in the nucleus of each element
Atomic Mass
the total number of protons and neutrons in the nucleus
Shells
contain electrons travelling at the same average from the nucleus
3 Classification of Elements
a. Metals good conductors of heat and electricity
b. Non Metals good insulators against heat and electricity
c. Metalloids borderline elements
Homogeneous Mixture
made up of components that cannot be easily distinguished even through the aid of a powerful microscope
Heterogeneous Mixture
made up of components that can be easily identified; either colloid or suspension
Solvent
substance present in largest quantity; most are liquids
Solute
substance present in smallest quantity; most are solids
Colloid/s
are substance/s consisting of very small particles suspended and dispersed in a medium such as air or water; contains particles smaller than those in suspensions but bigger than those present solutions
Compounds
made up of two or more different kind of atoms
Two Kinds of Compounds
A. Inorganic Compounds
B. Organic Compounds
4 Important Inorganic Compounds
- Water
- Oxygen and Carbon Dioxide
- Minerals
- Organic Salts
Water
makes up from 60 – 90 percent of the protoplasm and a universal solvent
special features of water
cohesion and expansion
Oxygen and Carbon Dioxide
present as gases in the respiratory organs and in the tissue fluids such as the blood and lymph
Minerals
trace elements needed in small amounts by plants, animals and human beings
12 Minerals in Living Things
- Calcium
- Chlorine
- Cobalt
- Copper
- Fluorine
- Iodine
- Iron
- Magnesium
- Manganese
- Phosphorus
- Sulfur
- Zinc
Iron
necessary to carry away carbon dioxide from the lungs to the cell and for the hemoglobin formation
Copper
needed by the body so it can use iron to build hemoglobin
Cobalt
needed for the formal function of all cells especially cells of the bone marrow, nervous system and gastro intestinal system
Magnesium
helps regulate muscle reaction and keeps the muscle in good working condition; plants needs magnesium to build
chlorophyll
Manganese
plays a role in the formation of urea
Zinc
an important factor in host immune defenses and in the acceleration of wound healing and normal sense of taste
Manganese and Zinc
required for the normal action of certain enzymes, without these two minerals, certain in the body cells would stop
Iodine
essential for the synthesis of thyroxine (hormone in the thyroid gland) and stimulates cell oxidation
Chlorine
found in Sodium Chloride
Flourine
found in water, tea, soybean, and seafishes
Organic Salts
present in skeletons; a term for table salt (sodium chloride, NaCl)
xeropthalmia
the surface of the eye becomes dry and likely to develop infection due to lack of Vitamin A
Vitamins
inorganic compounds, usually of plant origin, needed by man and animals for normal growth and development
There are _______ available but the body produces ______ of them.
13 vitamins; only 3
Vitamin A
(Retinol or Anti-Xeropthalmia); essential for normal bone and skeletal growth and also needed for healthy skin and formal night vision
Night blindness
an early symptom of vitamin A deficiency
8 vitamins of Vitamin B Complex
- B1 (Thiamine)
- B2 (Riboflavin)
- B3 (Niacin)
- B5 (Pantothenic Acid)
- B6 ( Pyridoxine)
- B7 (Biotin)
- B9 (Folic Acid)
- B12 (Cyanocobalamin)
Vitamin B1
Thiamine; necessary for good appetite, good muscle tones and for carbohydrates metabolism
Vitamin B1 deficiency
Beriberi
Vitamin B2
Riboflavin; needed for growth and for healthy skin and eyes and promotes the body’s use of oxygen in converting food into energy
Vitamin B6
Pyridoxine; Helps the body use amino acids and also needed for healthy teeth and gums, blood vessels, nervous system, and red blood vessels
