monosaccharides
oligosaccharides
polysacchrides - function of proteins?
-
provides support
store amino acids
transport mvmt of othr subs.
contractile mvmt
hormonal coordination actvity
acceleration of metabolism - 3 important nucleic acids are?
- DNA, RNA, ATP
- Eukaryotic
- contain nuclei(genetic material is enclosed)
- prokaryotic
- no nuclei(genetic material not enclosed)
- enzymes?
-
biological catalyst
1.speed up reactions
2.not changed in the process
3.same enzme will work in forward/reverse
4.enzymes are specific
5.enzymes are proteins - exergonic reactions
- store energy
- endergonic reactions
- store energy
- activation energy
- amt of energy required to start a reaction
- photosnthesis?
-
conversion of H2O & CO2 into sugars in the presence of light, O2 is released as a bi-product
---->occurs in chloroplast of plant - cellular respiration?
-
generates ATP
1. aerobic-requires O2
2. anerobic-doesnt require O2
