What is the definition of Transgenic?
1) gene located in healthy human 2) Gene is cut out using enzymes 3) Some bacteria contain rings of DNA called . These are . This is removed from a suitable bacterium. 4) The is cut open using the same enzymes as before 5) Insulin-producing gene is then into the plasmid using an called . 6) The recombinant DNA is inserted back into a 7) This bacterium now is a and will the gene and produce 8) As bacterium , more and more is produced. In order to , bacteria are placed in a where are closely monitored.
What is yoghurt?
Fermented Milk
Lactobacillus being killed
Milk and water juice
Sugar and yeast fermented
Lactose ––> Lactic acid + energy What does lactic acid do?
Causes yoghurt to become white
Decreases the pH
Makes the milk sweet
Sours the milk
Milk coagulates
Causes temperature to increase
Causes enzymes activity of milk to decrease
Makes sour-tasting yoghurt
❌ milk is used to avoid the presence of unwanted ❌. High temperatures kill the bacteria. The milk is cooled to ❌ - which is the optimum temperature for ❌. The enzymes from bacteria convert milk sugar (❌) into ❌. Which makes the milk ❌ and makes the product ❌.
Yeast cells contain enzymes that convert sugars into alcohol.
Yeast cells convert ethanol into sugar.
What is the process of producing the drink, beer called? What are the conditions needed?
Fermentation, aerobic respiration
Fermentation, all kinds of respiration
Fermentation, anaerobic respiration
Coagulate, anaerobic respiration
Making beer, aerobic respiration
1) Barley grains (containing ❌) are warmed with water to germinate. They produce amylase which breaks starch into maltose. 2) Barley is boiled with water to release ❌ 3) Hops are added for ❌ 4) ❌ is added and ❌ in this convert sugar to alcohol - ❌ 5) Beer is usually ❌ and the yeast is ❌ to make more beer.
The group of organisms that includes yeast are: Fungi Plants Protoctists Bacteria Animals( Fungi, Plants, Protoctists, Bacteria, Animals )
What is meant by the term anaerobic?
Describe how bottles can be sterilised with
Name the enzyme that digests the starch in the barley.
