Chapter 03-Cell Processes Flashcards
How are elements arranged on the periodic table?
by their properties
Where are the metals located on the periodic table?
on the left (and middle)
Where are the non-metals located on the periodic table?
on the right
What happens to the atomic number as you move from left to right across the periodic table?
it increases
Atom
smallest particle of matter that still has chemical properties of the element
Molecule
combination of two or more atoms
Element
Substance that cannot be broken down into simpler substances
Compound
combination of two or more elements
Chemical Bonds
join atoms together in a molecule
Chemical Equation
describes a chemical reaction. Starting materials on the left, end products on the right.
Endothermic
stores energy
Exothermic
releases energy
Carbohydrates
starches and sugars, major source of energy
Lipids
fats, oils and waxes. make up cell membrane
Proteins
make up muscles, antibodies, enzymes
