CATABOLISM AND ANABOLISM

catabolism

breaks down complex molecules to release energy

anabolism

consumes energy to create large molecules

is DNA and RNA synthesis anabolic or catabolic?

anabolic

why is DNA & RNA synthesis anabolic?

it builds simple nucleotides into complex nucleotides using energy

central dogma of cellular life

dsDNA → ssRNA → protein

transcription

DNA → RNA

is transcription anabolic or catabolic?

anabolic

what is transcription

it builds RNA from nucleotide monomers

translation

RNA → protein

is translation anabolic or catabolic?

anabolic

what is translation?

it assembles proteins from amino acids

uses organic molecules as carbon sources; can use a lot

heterotrophs

uses only carbon dioxide as principle carbon source; obtains energy from other sources

autotrophs

uses light to get energy

phototrophs

obtains energy from oxidation of chemical compounds

chemotrophs

uses inorganic compounds as their electron source

lithotrophs

uses organic compounds as their electron source

organotrophs
