Answer:
Characteristics of an Enzyme :
-Speed up chemical reactions.
-They are required in minute amounts.
-They are highly specific in their action.
-They are affected by temperature.
-They are affected by pH.
-Some catalyze reversible reactions.
-Some require coenzymes.
-They are inhibited by inhibitors.
Answer:
b) H2O → P680 chlorophyll a pair → PS II primary electron acceptor → Pq → cytochrome complex → Pc → P700 chlorophyll a pair → PS I primary electron acceptor → Fd → NADPH
Explanation:
The energy present in the photons is used to produce high energy electrons during the light chain of reactions. The H2O molecules generate P680 which is an excited chlorophyll molecule. Then the molecules are converted into pheophytin. The pheophytin produce special quinones which are QA and QB. This generates a plastoquinone pool.
Underground, at the point where slippage along the fault begins.
Ethonal is produced during b. Alcohol fermentation that converst sugars into ethanol.
