Cards

Term
How many ATP molecules are produced from one molecule of glucose during cellular respiration?
Definition
Net gain of 2
Term
What is the chemical equation for cellular respiration?
Definition
oxygen+glucose-->carbon+water+energy
Term
Order of Events in Cellular Respiration
Definition
Glycolosis, Krebs, Electron Transport
Term
What types of cells use fermentation?
Definition
Yeast, muscle cells and unicellular organisms
Term
Types of fermentation
Definition
Alcoholic and lactic
Term
Aerobic=
Definition
Requiring oxygen
Term
Why must cells divide?
Definition
The vol. increases faster than S.A. (makes it difficult to transport wastes) & there is not enough DNA to service cells larger than a certain size
Term
What is produced in the electron transport chain?
Definition
ATP
Term
When is DNA replicated in the cell cycle?
Definition
INTERPHASE
Term
Cycle cycle=
Definition
Grows, prepares for division, divides, starts over with 2 daughter cells
Term
What are chromatids?
Definition
Identical copies of DNA that make up a chromosome
Term
What are the stages of mitosis, in order, what do they look like, and what happens in each?
Definition
Prophase, Metaphase, Anaphase, Telophase
Term
Prophase
Definition
Chromatin condenses into chromosomes. Centrioles separate. Spindle beings to form. Nuclear envelop breaks down.
Term
Metaphase
Definition
Chromosomes line up across center. Each is connected to a spindle fiber.
Term
Anaphase
Definition
The sister chromatids separate into individual chromosomes, and are moved apart
Term
Telophase
Definition
The chromosomes gather at opposite ends of the cell and lose their distinct shapes. New nuclear envelopes form.
Term
Telophase
Definition
The chromosomes gather at opposite ends of the cell and lose their distinct shapes. New nuclear envelopes form.
Term
What are the two main stages of cell division?
Definition
Mitosis and interphase
Term
Events of the Cell Cycle
Definition
G1 Phase, S Phase, G2 Phase, M Phase
Term
G1 Phase
Definition
Grows
Term
S Phase
Definition
DNA is replicated
Term
G2 Phase
Definition
Prepares for mitosis (produces organelles)
Term
M Phase
Definition
Mitosis and Cytokinesis
Term
Cell Division
Definition
Mitosis and Cytokinesis
Term
Interphase
Definition
G1, S, G2
