Meiosis

The text discusses various biological concepts and processes, starting with meiosis and its role in genetics. It highlights the distinction between genotype, which encompasses an organism'

Meiosis

BIG IDEA 3

Hydrogen Bonding

Versaltility as a solvent

hydration shell

Ability to moderate Temperature

Specific Heat
Evaporate cooling
Heat of Vaporization

Cohesive Behavior

cohesion
surface tension
adhesion

Expansion upon Freezing

water expands while it freezes and the molecules moves slowly. Ex: rocks cracking

Biosphere

trees and white tailed deers
Deciduous forest

Cellular Respiration

Oxidative Phosphorylation

ETC and Chemiosmosis
26 or 28 ATP

Substrate Level Phosphorylation

Kreb Cycle (2 cycle)
1 FADH2
1 ATP
3 NADH+
2 CO2
Glycolysis
Investment

2 ATP used

Payoff

2 Pyruvate

2 NADH+

4 ATP formed

Chloroplasts

Calvin Cycle

consume 1 molecule of G3P, the calvin cylce consumes total of 9 ATP and 6 molecules of NADPH.
Sucrose
starch
Phase 3 ( Regeneration of the CO2 acceptor)
RUBP is prepared to recieve CO2 again and continue the cycle
Phase 2 (Reduction)
Phase 1. (carbon Fixation)
Does not use light

Light Reaction

Light photon strikes pigment molecule in PSII
Enzymes split

photoxcited

Use light

Replication

Enzymes

DNA ligase
DNA I
DNA Pol III
Primase
Topoisomerase
SSB

Eukaryotes

Replication occurs in the nucleus

Anitparallel arrangement

Complementary base Pairing

Prokaryotes

Replication occurs in the Cytoplasm

BIG IDEA 2

Big Idea 1

Meiosis

Dominant

Dominant alleles are written by capital letters

Phenotype

Organism's actual observed properties

BIG IDEA 3!!!!!

Recessive

Recessive alleles are represented by lower-case letters

Genotype

An organism's Full hereditary information even though not expressed
