digestion Flashcards
kilocalories and calories
bond energy
raise temperature of 1L of water by 1C
caloric values
(in ascending order)
proteins - must lose N; feed into glycolysis, krebs cycle, oxidative phosphorylation
CHO - production of co2
fats - feed into CHO metabolizing pathways
the Sun
ultimate energy source
photosynthesis
geothermal vents
extremely acidic
rich source of H2S
Mponeg Gold Mine
no light or heat
radioactive decay of elements supports growth of bacteria as source of energy for animals
oriental hornet
anti-reflective, light trapping bands
develops voltage gradient to drive ATP production
filter feeders
water with food is strained over gills or other structures to remove food
hematophagy
blood eaters
very efficient way to transmit infections - lyme disease, babesiosis
liquid digestion
highly specialized animals
adapted to food source
symbiotic relationship
parasites!
milk
mammalian trait
wide range of protein, fat and carbs
seawater
organic molecules at very low concentrations
uptake by active transport
very little energy per liter unless filtered
polyphyodont
teeth replaced
diphyodont
teeth not replaced
radula
invertebrates
analogous to teeth
proboscis
invertebrate elongated tube (no tongues)
protein metabolism
all animals require proteins and digest it in the same way (cannot produce all amino acids)
protein digestion requirements
high acidity
protease activity
amino acid types
acidic
basic
lipophilic
neutral
