What factors can change the efficiency of enzymes? 1 What factors can change the efficiency of enzymes? answer Change in pH or temperature Calderglen High School

Give examples of alcoholic drinks and the number of units they have. 2 Give examples of alcoholic drinks and the number of units they have. answer Small glass of wine – 1 unit Spirit measure - 1 unit Pint of beer or lager – 2 units Calderglen High School

The alcohol produced during fermentation is ……….? 3 The alcohol produced during fermentation is ……….? answer Ethanol Calderglen High School

Calderglen High School 4 The water and alcohol mixture formed in the fermentation reaction be separated by ……? answer Distillation The process can also be used to increase the concentration of fermentation products Calderglen High School

How are alcoholic drinks made? 5 How are alcoholic drinks made? answer Alcoholic drinks are made by fermenting any fruit or vegetable which is a source of sugars. An enzyme produced by yeast acts as a catalyst for the reaction Calderglen High School

The breakdown of carbohydrates to form alcohol 6 Fermentation is……..? answer The breakdown of carbohydrates to form alcohol Calderglen High School

Calderglen High School 7 Give examples of alcoholic drinks and the source of carbohydrate from which they are made. answer Wine = grapes Cider = apples Whisky = barley Vodka = potatoes Calderglen High School

Give some products (apart from food) which can be made from plants? 8 Give some products (apart from food) which can be made from plants? answer Medicines Alcohol Calderglen High School

Name a plant used to make ethanol for fuels? 9 Name a plant used to make ethanol for fuels? answer SUGARCANE Calderglen High School

Name a product you could get from poppies? 10 Name a product you could get from poppies? answer Morphine (medicine) Calderglen High School
