Enzyme Activity Lab Background Notes
Enzymes: speed up chemical reactions in biological systems by lowering the activation
Form enzyme-substrate complex that lower activation energy required
Specific shape and structure to determine their functio
The Origin of Life thanks Louie!
If all life comes from preexisting life
(biogenesis), then how could there have
been a common ancestor?
What is spontaneous generation? Does it
Could it have happened on early earth (what
were conditions like)?
Ch. 32 Notes
Diverse Forms, Common Challenges
Anatomy: biological forms
Examining anatomy often gives clues to physiology: biological function
Feedback Control Maintains the Internal Environment in Many Animals
Hierarchical Organization of Animal Bodie
A Russo the Great Production
To continue, life depends on it.
Whats another way to think of
What does cell division do for
How does cell division do it?
Replicates the genome and passes it
along to daughter cells.
So check this out.
Something else that prokaryotic and eukaryotic
cells have in common?
The ability to do such a great job deciding when and
where genes are turned on or off (or expressed).
Why do we need to alter how our genes are expressed?
What do we
Phylogenies are based on common ancestries inferred from evidence
Sedimentary rocks are the richest source of fossils
Fossil record: based on the sequence i which fossils have accumulated in layers
of sediments, called strata
AP Biology: Chapter 24 The Origin of Species
What Is a Species?
1. Distinguish between anagenesis and cladogenesis.
anagenessis: the accumulation of heritable changes, altering the characteristic of the species
cladogenesis: branching evolution, in which
