Bio 260 Ch5 A metabolism
Metabolism: Sum of all biochemical reactions in cell
catabolism: breaking down for energy
Why: Harvest energy to power life
How: Make your own or steal someone else's
Anabolism: Using energy to build stuff/get bigger What: synthesize new parts (grow, heal, maintain)
Eg. Cell Wall, Membranes, ribosomes, DNA
animals and fungi: -steal materials
-Break down organic chemicals in food
Plants: -Make it
Make their own food and break it down
Microbes: - it depends
-diverse
-Some are hetertrophs
-some photoautotrophs
Heterotrophs (other feeding): An organism that obtains organic food molecules by eating other
organisms or their by-products.
Energy and Carbon from organic chems in food
Photoautotrophs: Organisms that use light as a source of energy to synthesize organic substances.
1/5
, Carbon from inorganic CO2
Chemolithoautotrophs: Rock self feeding inorganic rocks
Microbial metabolism affects us: -in Lab our metabolism in an easier model
In the clinic
Differences exploited for drug design and treatment
In the wild
Making energy recycling nutrients
-Tech
Synthesis of useful products: degration + polution
In classroom
Focused on structure that allows us to study, ID and kill
