Term
metabolism
Definition
-the process to cast change/”The total of the chemical processes in a cell. It includes catabolism and anabolism."
Term
anabolism
Definition
–the process to cast up/ “Process of building up complex materials (proteins) from simple materials. Anabolism produces proteins such as hormones and enzymes that are important to growth of cells. Anabolism occurs in the endoplasmic reticulum of a cell.”
Term
catabolism
Definition
–the process to cast down/”Process of breaking down complex materials (foods) to form simpler substances and release energy.”
Term
cell membrane
Definition
–“Stucture surrounding and protecting the cell. It determines what enters and leaves the cell.”
Term
endoplasmic reticulum
Definition
–“Structure (canals) within the cytoplasm. Site in which large proteins are made from smaller protein pieces. Anabolism takes place on the ribosomes of the endoplasmic reticulum.”
Term
DNA
Definition
deoxyribonucleic acid/“Chemical found within each chromosome. Arranged like a sequence of recipes in code, it directs the activities of the cell.”
Term
nucleus
Definition
–“Control center of the cell. It contains chromosomes and directs the activities of the cell.”
Term
mitochondria
Definition
–“Structures in the cytoplasm in which foods are burned to release energy. Catabolism takes place in the mitochondria.”
Term
chromosomes
Definition
–bodies of color/ “Rod-shaped structures in the nucleus that contain regions of DNA called genes. There are 46 chromosomes (23 pairs) in every cell except for the egg and sperm cells, which contain only 23 individual, unpaired chromosomes.”
Term
cytoplasm
Definition
"All the material that is outside the nucleus and yet contained within the cell membrane."
Term
genes
Definition
"Regions of DNA within each chromosome."
Term
