respiration + classifiying organism Flashcards
what do organisms need energy for
chem reactions
muscle contractions
keeping warm
aerobic respiration chem formula
C6H1206+6O2—->6CO2+6H20 + ATP
- glucose + oxygen —> carbon dioxide + water + ATP
- energy is transferred via the molecule ATP
aerobic respiration
requires oxygen
complete glucose breakdown
a large amount of energy released for cell process and reactions
anaerobic respiration formula (yeast/plants) + fermentation
glucose–> alcohol + carbon dioxide
fermentation - manufacture of bread and brewing of alcohol
why is lactic acid made in anaerobic
- oxygen runs out —-> glucose is broken down without it—-> producing lactic acid
- Glucose has not been fully broken down
anaerobic respiration
small amounts of energy released
products in animals - lactic acid
products in yeast- carbon dioxide + ethanol
glucose breakdown incomplete
describe fungi (eukaryote)
- contains mycelium + hyphae
- chitin cell wall
- e.g Mucor and Yeast
- feed via saprotrophic nutrition
- stores carbs as glycogen
describe protist (eukaryote)
- single celled
- animals like = amoeba
- plant like + chloroplasts = chlorella
what are prokaryotes
- no nucleus or membrane bound organelles
describe bacteria ( prokaryotes)
- meurin cell wall
- no nucleus
- cytoplasm + plasmid loops of DNA
- e.g lactobacillus and pneumococcus
describe virus ( pathogen)
- disease causing organism
- e.g HIV —> AIDS
- non living// no respiration
- NO cellular structure ONLY protein coat of dna or rna
describe bacterial + proticits and fungal pathogenic traits
- salmonella
- malaria
- athletes foot
is CO2 is present the sodium hydrogen carbonate indicator will turn….
and when its respiring
- red
- yellow cause CO2 produced
abiotic factors
- temp —> affects enzymes
- oxygen —> respiration
- water—> activates enzymes/chem reactions
- pH —-> affects enzymes
biotic factors
- age/species/type/mass
- diseases
- new preadtors
- competition
