metabolic diversity

metabolism

biochemical reactions

catabolism

chemical break down of molecules

anabolism

chemical building of molecules

what are energy storage molecule?

ATP

what is an organic molecule?

a molecule that has a carbon-hydrogen bond

what does litho mean?

rock eater

how do autotrophs fix CO2?

convert inorganic carbon gas int organic molecules

what do microbes use when they convert light into energy?

photosystems

which photosysten occurs first?

photo system 2

why does photo system 2 come before 1?

photo system 1 was discovered first and they never renamed them

what occurs in photo system 2?

use light energy and split water to make oxygen

how does photo system 2 work?

Protons are pushed across the membrane and create hydrogen ions(proton imbalance)

what occurs in photo system 1?

use light energy to generate NADPH (storage molecule)

What does it mean if NADPH has an H?

it is a storage molecule

what does ATP synthase make?

ATP

oxygenic

produces oxygen

who uses classic photosynthesis?

photolithoautotrophy

photolithoautotrophy

Photosynthesis

what bacteria do photosynthesis?

purple surfer bacteria

how do purple sulfer bacteria grow?

in anaerobic conditions

what does anaerobic mean?

no oxygen, they do not produce O2 and lack a photosystem

what types of photolithoautotrophy are there?

aerobic and anaerobic

where do purple sulfer bacteria live?

shallow microbial mats and shallow water sediments

Bacteria and archaea that use light in strange ways are what?

photooganoheterotrophs

where do Bacteria and archaea that use light in strange ways live?

in aerobic waters

are Bacteria and archaea that use light in strange ways oxygenic or anoxygenic?

anoxygenic

photoorganoheterotrophy

gets its energy from light and uses organic compounds, but gets carbon from pre-existing molecules
