CyfarthfaB2CellProce

QuestionAnswer
Two molecules that firm an alternating pattern in the DNA backbone Sugar and phosphate
Four different molecules that make up the genetic code Bases
The Base that pairs with adenine Thymine
The Base that pairs with cytosine Guanine
The name given to a group of three bases that provides a code Triplet code
What is made using the triplet code? Specific Amino acid
Formed when amino acids join together Protein
A change in the DNA Mutation
Consequence of a mutation on the outcome Different triplet code = different amino acid = different protein
Definition of enzyme Biological catalyst
What are enzymes made of? Protein
Molecule that fits into enzyme Substrate
Specially shaped area of enzyme Active site
Formed when enzyme and substrate join Enzyme -substrate complex
Enzyme's active site has permanently changed shape Denatured
Consequence of active site being denatured Substrate can no longer fit into active site so reaction cannot taken place
Explain effect of temperature on enzyme activity Initially = more energy, more collisions & enzyme - substrate complexes formed = higher rate. After optimum = enzymes denatured = lower rate
Best temperature or pH Optimum
Everyday use of enzymes Biological washing powder
Enzymes that break down carbohydrates Carbohydrase
Building blocks of carbohydrates (starch) Glucose
Enzyme that breaks down fats Lipase
Building blocks of fats Fatty acids and glycerol
Enzyme that breaks down protein Protease
Building blocks of protein Amino acids
Reason for using low temperatures with biological washing powders Higher temperature would denatured enzymes
Environmental benefits of biological washing powder Lower temp wash = less energy/ electricity = less fossil fuels burned in power station = less CO2 = less global warming

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
