respiration Flashcards
define respiration
a series of controlled reactions
what is used for respiration
ATP
where does respiration occur
in the mitochondria
why does respiration occur in the mitochondria
have their own DNA and Ribosmomes to manifacture their own respiratory enzymes
isolated enviroment
has cristea - increase surface area
give features of the mitochondria
a space between the inner and outer membrane
outer membrane contains porins that allow ions to move through
inner memrane space called matrix contains DNA RNA and where the krebs cycle occurs
what does the matrix contain
DNA and RNA
what reaction occurs in the mitochondria
krebs cycle
what are the four stages of respiration
glycolisis
link reaction
krebs cycle
electron transport chain
where does glycolisis occur
in the cytoplasm of the cell
here does the link reaction occur
matrix
here does the kreb cycle occur
matrix
here does electron transfer chain occur
utalises protiens found in the membrane of the crista
why is ATP used
it provides instant energy as it only needs one hydrolisis reaction to break it down
what is phosphorilation
adding a phosphate molecule
what phosphorilation reaction occurs during respiration
a single reaction involving direct transfer of a phosphate group from a doner molecule of ADP
