- structures within the cells that perform specialized functions are
- the control center of a cell; contains DNA; controls growth and reproduction
- a small dense area inside the nucleus; ribosomes are made here
- rigid, inflexible structure that gives the cell structure and protection; found outside the cell membrane; made of polysaccharide cellulose; not selectively permeable; only in plant cells
- has a nucleus and membrane bound organelle
- outer boundary of the cell that regulates which materials enter and exit the cell; seperates the cell from the external environment; made of a phospholipid bilayer; are selectively permeable
- has no nucleus and no membrane bound organelle; has DNA
- a threadlike genetic material found in the nucleus; a strand of DNA
- sac-like structures used to store water, salts, proteins, carbs, food, waste, and other materials; larger in plant cells
- double membrane that separates the nucleus from the cytoplasm; made of proteins and phospholipids
- clear jelly-like fluid inside the cell; main component is water
- Select all of the cellular conditions that affect enzyme activity.
- After a product is released from its active site, a(n) ______ can be used again in another reaction because it is not consumed or altered in the reaction.
- A product molecule blocks enzyme activity by binding to a location other than the active site during ______ inhibition; on the other hand, a product molecule blocks enzyme activity by binding directly to the active site during ______ inhibition.
- Competitive and noncompetitive inhibition are two mechanisms of
- Phase cell is found in for most of its' life cycle.
- Cancer cells tend to have a defect in a particular gene, what is that gene called
- Chromatin coils, condenses, becomes visible.
- The nuclear membrane, and nucleoli reappear.
- Centromeres break and chromosomes start to move toward opposite poles of the cell.
