enzyme
biological catalyst which speeds up chemical reactions because it lowers the activation energy
1 of 17
competitive inhibtio n
substrate and inhibitor are chemically similafr, inhibitor binds to the active site so the substrate is unable to bind , enzyme activity is prevented
2 of 17
non competitive
substrate and inhibitor are different and the inhibitor binds to another active site, however this chnages shape of the active site so the substrate is unable to bind
3 of 17
metabolic pathways
all reactions take place inside cells, some build up nmetabloic organic pathways and some break them down
4 of 17
oxidation
gain of oxygen and loss of hydrogen and electrons
5 of 17
reduction
loss of oxygen and gain of hydrogen and electrons
6 of 17
glycolosis
phosporolation= 2 phosphate groups are added to a molecule of glucose forms hexose bisphosphate. lysis= spilts into 2 forms of triose phosphate. oxidation= 2 hydrogens are removed converts into 2 ATP makes 2 pyrovates
7 of 17
mitoncondiran
has double membrane, matrix, inner membranes, ribosomes and outer membrane
8 of 17
link reaction
oxidation of pyrovate= H is removed and accepted by coenzyme A. Decarboxylation= co2 removed forms 2 carbon acetyl compound. formation coenzyme= compound attaches to enzyme to form 2 carbon acetyl coenzyme A
9 of 17
krebs cycle- in mitocondria-matrixq
decarboxylation= removal of co2.... oxidation= removal of hydrogen FAD produces FADH +H
10 of 17
Photosynthesis
production of carbon compounds using light energy
11 of 17
effects on earth
prokaryotics were first to carry it out, reduced co2, reduces green house gases, increases rise in 02
12 of 17
chlorophyll
has stroma, granum, thylakoid membrane, double membrane and startch grain
13 of 17
dependent- relys on the sun
1.light absorbed by chlorohyl, ground state electron increase energy 2. passed to elec transport chain 3.electron to photo 1 4.hydrogen passes into membrane 5. produces ATP and NADPH +H
14 of 17
independent
carbon fixation= RuBp comines with co2 and splits to form glycerate phosphate reduction= glycerate reduces using NADPH and ATP and it form triose phos . regeneration of RuBp= molecules of TP are metabloised systheis= lipids, amino, sugar
15 of 17
electron transport chain
passes electrons between carriers in membrane, happens as energy is released, last acceptor is 02
16 of 17
phosphorolation
hydrogen ions pumped into the membrane, inceases gradient in matrix
