Definitions and key terms related to cell biology, including the concept of cell theory, different types of cells such as bacteria, archaea, and eukaryotes, the structure and functions of various organelles like the plasma membrane, nucleus, mitochondria, ribosomes, and more. It also covers the differences between prokaryotic and eukaryotic cells, the functions of macromolecules, and the role of energy in cells.

DEFINITION 3 Share characteristics of prokaryotes but have different biochemistry TERM 4
DEFINITION 4 Eurkaryotes nucleus TERM 5
DEFINITION 5 Eukaryotes increased complexity Membrane-bound cytoplasmic compartments Membrane-bound nucleus Cytoskeleton DNA wrapped around histone proteins
Phospholipids Proteins Glycolipids Glycoproteins TERM 7
DEFINITION 7 selective barrier perception, communication, respond to environment ability to take in nutrients ability to release wastes regulate water intake/output TERM 8
DEFINITION 8 Double membrane-bound( envelope) pores to cytoplasm, regulated traffic contains the chromosomes nucleolus-no membrane, creates ribosomes TERM 9
DEFINITION 9 Similar to bacterial cells double-membrane contain circular DNA model main function is to generate large amounts of ATP Tricarboxylic acid cycle ATP synthesis Lipid oxidation TERM 10
DEFINITION 10 Cytoplasmic ribo-protein structure contain RNA and protein Free or bound to endoplasmic-reticulum Ribozymes-nano-machines: polymerize amino acids to polypetides Not Membrane-bound Smaller than organelles
Membrane-bound vessicles travel between Rough ER and Golgi Movement is controlled - it is not diffusion Other vesicles leave the Golgi and fuse with the plasma membrane TERM 17
DEFINITION 17 bound by a single membrane contain strong enzymes that degrade macromolecules created by rough ER, packaged in a vesicle TERM 18
DEFINITION 18 bound by a single membrane all hydrogen peroxide creating reactions are carried out here contains catalase to degrade hydrogen peroxide oxidizes long chain fatty acids metabolizes alcohol TERM 19

DEFINITION 22 monosaccharide amino acid nitrogenous base TERM 23
DEFINITION 23 Saccharides hydrates of a carbon have suffix -ose longer carbohydrates can switch between cyclic and non- cyclic TERM 24
DEFINITION 24 many monosaccharides bonded together by glycosidic bonds they differ only in type of glucose bod (alpha or beta) and linkage TERM 25
DEFINITION 25 The chains are formed by alpha 1,4 glycosidic bonds The branches are formed by alpha 1,6 glycosidic bonds
Contains a phosphate in place of one of the fatty acids and alcohol TERM 32

DEFINITION 48 the study of various types of energy transformations that occur in living organisms In order to maintain itself a cell must acquire and expend energy TERM 49
DEFINITION 49 The study of changes of energy that accompany events in the universe Use it to predict direction events take, whether or not energy is needed to make them happen TERM 50
DEFINITION 50 energy of an object by virtue of its position; stored energy
energy of motion TERM 52
DEFINITION 52 store energy lose or gain energy in the form of heat from the environment lose or gain energy by doing work or having work done on it
