Cell Biology Flashcards
What happens when enzymes are denatured
When enzymes are denatured the amino acids break and the shape of the active site changes so the substrate no longer fits
what is an enzymes role?
Enzymes speed up the rate of all biochemical reactions. They allow Biochemical reactions to proceed rapidly at the relatively low temperatures.
Where are enzymes found?
Enzymes are found in living cells.
Name three structures or parts shown to be present in a plant cell and animal/human cell 
Nucleus
Cytoplasm
Cell membrane
Name a structure that would be found in a plant cells but not in a root cell
Chloroplasts.
Name a substance added to make cell structures more visible when viewing with microscope
Stain
What’s the one with the blood cells can fight infection?
By engulfing bacteria and producing antibodies.
What substance forms blood clots ?
protein
Name the raw materials of photosynthesis?
Carbon dioxide and water.
What is the green chemical which plants need to carry for photosynthesis called?
Chlorophyll
What are chemical substance are enzymes made of?
enzymes are made of protein/amino acids
What is a catalyst?
A catalyst is a material that speeds up the chemical reaction while remaining unchanged
Give an example of a geneticallly engineered Protein and what Is it used for?
Insulin and that is used to treat diabetes.
What is meant by the term synthesis reaction?
Smaller substrate molecules are built up into larger products.
 how would a change in the DNA affect a protein?
There would be a difference in structure/shape
