Components of the Cell Flashcards
Makes up each element
Smallest unit of matter
Atom
cannot be split into a simpler substance
Element
Atom or molecule with positive or negative charge
Ion
2 or more atoms sharing electrons
Molecule
contains atoms of two or more different elements
compound
cytoplasm
nucleus
plasma membrane
cell
contains both carbon and hydrogen
usually called nonelecrtolytes
organic compound
contains atoms of carbon, hydrogen, and oxygen
water soluble molecules
glucose, table sugar and plant starch
carbohydrates (organic substance)
contains atoms of carbon, hydrogen, and oxygen
insoluble in water soluble in organic solvents
fatty acids are the simplest
phospholipids and steroids
lipids (organic substances)
contains atoms of carbon, hydrogen, oxygen, and nitrogen
building blocks are amino acids
shapes are complex
keratin, fibrin, a myglobin
proteins (organic substance)
contains atoms of carbon, hydrogen, oxygen, nitrogen, and phosphorus
building blocks are nucleotides
nucleic acids (organic substance)
two major types of nucleic acids
RNA and DNA (organic substance)
energy currency of living systems
powers cellular activities that require energy called Endergonic Reactions
ATP
provide energy
provide cell structure
carbohydrates
provide energy
provide cell structure
provide insulation beneath the skin
lipids
