5 Written Questions

1. the process by which a cell divides into 2 new daughter cells
2. uses high-energy electrons from the Krebs Cycle to convert ADP into ATP
3. the third phase of mitosis where the centromeres split allowing the chromatids to seperate and become individual chromosomes.
4. tiny structures located in the cytoplasm near the nuclear envelope. they seperate and take up positions on opposite sides of the nucleus.
5. the second stage in the division of the cytoplasm

5 Matching Questions

1. chromatids
2. cylins

4. prophase
5. interphase

1. a two identical "sisters" that are connected during the process of cell division and seperate when the cell divides. These make up a chromosome.
2. b regulate the timing of the cell cycle in eukaryotic cells.
3. c the second stage of cellular respiration that breaks down pyruvic acid into carbon dioxide in a series of energy extracting reactions.
4. d the "in-between" period between cell divisions.
5. e the first and longest phase of mitosis in which the chromosomes curl up and around each other and become visible.

   True        False

2. centromere → the area where each pair of chromatids are attached near the middle.

   True        False

3. glycolysis → the process in which one glucose is broken in half, producing 2 molecules of pyruvic acid, a 3 carbon compound.

   True        False

4. fermentation → tiny structures located in the cytoplasm near the nuclear envelope. they seperate and take up positions on opposite sides of the nucleus.
