生 物 科 問 題

我也是讀bio

1a
N是活性部位,M是受質,O是酶,P是產物
1b
因為酶在反應中不會被消耗,可重複使用
1ci
當低過最低溫度時,酶的活性隨溫度上升而增加,這是因為酶份子和受質份子的動能上升,因而增加互相碰撞的機會,形成更多酶受質複合物,產生更多產物
1cii
高溫令酶的活性部位改變,不能和受質結合,失去催化力

m=受質分子 n=活性部位 O=西每
B.因為西每可重復使用,在反應後他不會改變形狀/消耗
c.因為西每活性會隨溫度增加而上升,所以反應速率捉高
cii.唔係幾明講咩

2a) m=Substrate
o= enzymes
n= active site


2b) For the enzymes, it is break down protein. So no mater how much, it still break down.

2c1) If the temperature is high, the rate of reaction will be high.

Only those collisions equal to orgreater than the activation energy of a reaction will lead to form a product.Increasing temperature will increase the energy of the reacting particles. As aresult, the particles move faster and more particles move faster and moreparticles having sufficient energy to overcome the activation energy. Thereforethe number of effective collisions increases. The higher the temperature, thegreater the rate of reaction.
2c11) When the temperature is high, and finish the reaction. The substrate will change the shape and no fit the enzymes. Like the picture 4.
