Chapter Two Flashcards
Catabolism
- breaking down food
* releases energy
Cell membrane
- around the cell
- protects the cell
- determines what enters and leaves
Chromosomes
- rod-shaped
- in the nucleus
- contains DNA (genes)
Cytoplasm
- outside the nucleus
* in the cell membrane
DNA
- in chromosomes
* directs activities of the cell
Endoplasmic reticulum
- large proteins are made from smaller ones
* anabolism in ribosomes
Genes
•regions of DNA within each chromosome
Karyotype
- picture of chromosomes in a nucleus
* numerical order
Metabolism
- the total of the chemical processes in a cell
* catabolism and anabolism
Mitochondria
- foods are burned to release energy
* catabolism
Nucleus
- control center
- chromosomes
- directs activity of the cell
