Cards

Term
What are two types of electron carriers? 
Definition
NADs and FADs
Term
What are the two types of phosphorilation?
Definition
Substraight (Simple) and Oxidative (Complex)
Term

The coupling of electron transport chain and the proton gradient is ______.

Definition
Chemiosmosis
Term
Phosphate group + ATP (Energy) =
Definition
ADP
Term
The cellular process responsible for almost all of the adenosphine triphosphate (ATP) harvested from food and for all the ADP produced by photosynthesis.
Definition
Chemiosmosis
Term
Carbs can convert into _________?
Definition
Glucose
Term

The process by which plants, algae, and some bacteria use the energy of sunlight to create from carbon dioxide and water the more complicated molecules that make up living organisms.

Definition
Photosynthesis
Term
Genes on chromosomes that determine characteristsics
Definition
Meiosis
Term
A special form of nuclear division that precedes gamete formation in sexually reporducing eukaryotes.
Definition
Meiosis
Term
Hereditary units that are represented as segments of chromosomes.
Definition

Genes

Term
Chromosomes contain two genes each.  True or False?
Definition
False.  They carry thousands of genes.
Term
DNA is made up of ________ building blocks.
Definition
nucleotide building blocks.
Term
What are the four major building blocks of DNA?
Definition
Adenomine, Cytosthene, Guanine, Thiamine
Term
Each individual gene is responsible for many different traits.  True or False?
Definition

False, Each gene is responsible for one trait. 

Term
The gene's locations is called its ______.
Definition
Locus
Term
Genes move form chromosome to chromosome. T or F?
Definition
False.
Term
One of the two nearly identical verisons of each chromosome. Chromosomes that associate in pairs in the first stage of meiosis.
Definition
Homologous Chromosome (Greek fro homologia, meaning agreement)
Term
You get __ sets of chromosomes from each of your parents.
Definition
22
Term
Chromosome numbers are the same in every species.  T or F?
Definition
False.
Term
Mitosis is for _____ cells.
Definition
Somatic
Term
The M phase of cell division in which the microtubular apparatus is assembled, binds to the chromosomes, and moves them apart.  This phase is the essential step in the separation of the two daughter cell genomes.
Definition
Mitosis
Term
Stage of meiosis in which we have doubled our #, producing gametes.  This is when replication occurs.
Definition
Divison one of Interphase
Term
Binary fission
Definition
Asexual Reproduction
Term
Happens in interphase when things are so close they combine.
Definition
Tetrad
Term
Intermingling process, wrapping around, connecting to eachother occurs in the tetrad during interphase and during the "crossing over".
Definition
Synapsis
Term

The phase of meiosis when chromatids line up and the spindle is formed. The tetrad is on the fiber in the center or equator.

Definition
Metaphase 1
Term

The phase of meiosis when the chromatids move to opposite poles of cell and segreagation takes place.

Definition
Anaphase 1
Term
The stage of meiosis in which we then have two cells.  Cytokenisis occurs (the division of cytoplasm and organelles).
Definition
Telephase 1
Term
The C phase of cell division in which the cell itself divides, creating two daughter cells.
Definition
Cytokinesis
