Term
Anaerobic Respiration (Fermentation)
Definition
One of two metabolic pathways in which ATP is released. (Does not require oxygen)
Term
Aerobic Respiration
Definition
One of two metabolic pathways in which ATP is released. (Does require oxygen)
Term
Glucose
Definition
Supplies energy for aerobic and anaerobic respiration.
Term
How does oxygen affect aerobic respiration?
Definition
Oxygen mixes with glucose to create energy for the process.
Term
How does oxygen affect anaerobic respiration?
Definition
It occurs when oxygen levels are low.
Term
What metabolic pathway releases the MOST energy for organisms?
Definition
Aerobic Respiration
Term
What are the 3 stages of aerobic respiration and in what order do they occur?
Definition
Glycolysis, Kreb's Cycle, Electron Transport Phosphorycation Chain (in that order)
Term
What reactants go into Glycolysis and what are the products?
Definition
Glucose goes in and is cut into two pyruvates by the enzymes. Product: 2 ATP's.
Term
What reactants go into Kreb's Cycle and what are the products?
Definition
The pyruvates go in and are broken down into carbon. Product: 2 ATP's
Term
What reactants go into Electron Transport Phosphorycation Chain and what's the product?
Definition
In mitochondria, electrons are transported by enzymes to oxygen. Product: 32 ATP's.
Term
Genes
Definition
Instructions for a particular trait which has a specific location on a chromosome.
Term
How are genes transmitted to offspring?
Definition
Each parent gives one gene for each trait in a diploid cell.
Term
Dominant Allele
Definition
More common alleles that dominate over recessive alleles
Term
Recessive Allele
Definition
Less common allele that hides under dominant alleles.
Term
Heterozygous trait
Definition
A trait that contains both a dominant and recessive allele.
Term
Homozygous Allele
Definition
A trait that contains either two dominant or two recessive alleles.
Term
Genotype
Definition
The genetic make up of a trait.
Term
Phenotype
Definition
The physical, observable trait.
Term
Gene Pair
Definition
2 genes at a homologous location
Term
Mendel's Principle of Segregation
Definition
Gene pairs seperate during gamete formation. (Each gamete gets one gene)
Term
Mendel's Principle of Independent Assortment
Definition
Each gene pair sorts itself into gametes independently from other gene pairs.
Term
Monohybrid Cross
Definition
A cross between heterozygous parents (one trait)
Term
Dihybrid Cross
Definition
A cross between two offspring containing 2 traits of interest instead of just one.
Term
Glycolysis
Definition
First step in aerobic respiration. Cuts glucose into 2 pyruvates. Gains 2 ATP.
Term
Kreb's Cycle
Definition
2nd step of aerobic respiration. Pyruvates are broken down into CO2. Gains 2 ATP.
Term
Electron Transport Phosphorycation Chain
Definition
Final step of aerobic respiration. Enzymes transport electrons to O2. Gains 32 ATP.
