2 Terms Flashcards
Terms Pertaining to the Body as a Whole
process of building up large proteins from small protein pieces called amino acids
anabolism
process whereby complex nutrients are broken down to simpler substances and energy is released
catabolism
structure surrounding and protecting the cell; determines what enters and leaves the cell
cell membrane
rod-shaped structures in the nucleus that contain regions of DNA called genes
chromosomes
46 (23 pairs) in every cell except for the egg and sperm cells, which contain only 23 (individual, unpaired)
chromosomes
all of the material that is outside the nucleus and yet contained within the cell membrane
cytoplasm
chemical found within each chromosome; arranged like a sequence of recipes in code; directs the activities of the cell
DNA
network of canals within the cytoplasm of the cell; place where large proteins are made from smaller protein pieces
endoplasmic reticulum
regions of DNA within each chromosome
genes
picture of chromosomes in the nucleus of a cell; chromosomes arranged in numerical order to determine their number and structure
karyotype
total of the chemical processes in a cell
metabolism
includes catabolism and anabolism
metabolism
structures in the cytoplasm that provide the principal source of energy (miniature “power plants”) for the cell; catabolism occurs here
mitochondria
control center of the cell; contains chromosomes and directs the activities of the cell
