describe the element composition of lipids C, H, O, P with H:O much great than 2:1
describe the element composition of nucleic acids C, H, O, N, P
what is the function of an enzyme to control the rate of the chemical reactions during metabolic activity
list the characteristics of the enzyme proteins with specific shapes, affected by heat and pH, they are biochemical catalysts, they work both inside and outside cells
what lipids are associated with cell membranes phospholipids
fats and oils are lipids that are composed of 3 fatty acids and 1 glycerol; what are they called triglycerides
animals store their energy long term as fats and oils
the monomers of nucleic acids are nucleotides
what are the sugars of DNA and RNA deoxyribose and ribose
what are the functions of the nucleic acids store hereditary information
what best describes the shape of the DNA molecule double helix

quote the 3 components of the Cell Theory 1. all life is cellular 2. all life functions by their cells 3. all cells come from preexisting cells by cell division
cells with an organized nucleus eukaryote
cells lacking an organized nucleus prokaryote
the green organelle chloroplast
what controls the substances entering and leaving the cell selectively permeable membranes; cell membrane

how do I calculate total magnification on a microscope objective X ocular (10X)
who named the cell and what was he looking at Hooke; cork cells
who was the first to see living cells Von Leeuwenhoek
what organelle stores food vacuole
