Plant bio exam 2
Explanation of photosys 2 and 1
-occurs in thylakoid membrane
-photosys 2 oxidizes water and transports electrons
-photosystem one generated NADPH
Goal: to generate ATP
Photosystem 2 called photosystem 2 because it was discovered second.

ADHESIVE PROPERTIES OF BYSSAL THREADS
The constant changing in the frequencies of alleles across the animal
kingdom is no new concept. The evolution of most modern phylas of animals
occurred after the Cambrian Explosionabout 542 million years agoforever
What genes express is determined by the nature of the infecting phage: Lytic vs.
The phage genome first enters the host bacterial cell, and phage genes are expressed
at specific times:
Early (right after infection)
Serine Proteases (Chymotrypsin):
Protease: an enzyme that catalyzes the hydrolytic cleavage of peptide bonds
Chymotrypsin is a serine protease that functions best at the slightly basic pH = 8.0
and provides a rate enhancement of 9 orders of magnitude.
Three major types of catalysis:
1. General Acid/Base catalysis:
Unstable charged intermediates break down rapidly to reactants; these can
be stabilized by proton transfer to form species that break down more
rapidly to products
Biological Catalysts: Enzymes
Large Reaction rate acceleration generally around five to seventeen orders
Function in aqueous solutions with mild temperatures and pHs
Cofactors: inorganic ions, metal
Breaking and Entering
Or in Other Words: Phage Replication
Phage Replication Five Major Steps:
3. Tail Contraction
5. DNA Injection
Phage replicate by infecting a host and overtaking every day host cell regular
Phage and Bacteria Introduction
Cells contain a cytoplasmic membrane, genetics material (DNA), and a means to
express the DNA.
Conserved Functions: Replication, Metabolism, Adaptation
Bacterial Phage overtake these functions to promote their own survival

The Heart Muscle
The heart is the most important
muscle in the body.
You cannot live without a heart.
The heart is really a pump or two
pumps in one. The right side receives
blood from the body and pumps
Neat Fact Your heart beats about 100,000 times in one day and about 35 million times in a
year. During an average lifetime, the human heart will beat more than 2.5 billion times.
