Cell Organisation and Enzymes Flashcards
Cell-
(definition)
a basic building block that all living organisms have
tissue-
(definition)
a group of similar cells that work together
organ-
(definition)
a group of different tissues that work together
organ system-
(definition)
a group of organs working together
Organ systems work together to make entire _________
Organ systems work together to make entire organisms
Enzymes ________ chemical reactions
Enzymes catalyse chemical reactions
Each enzyme only catalyses one specific ________ because of the unique shape of its ______ ____
Each enzyme only catalyses one specific reaction because of the unique shape of its active site.
High ____________ and high and low ___ change the shape of the ______ ____ so the enzyme __ ______ works
High temperatures and high and low pHs change the shape of the active site so the enzyme no longer works
What is it called when an active site changes shapes?
the enzyme is DENATURED
_________ enzymes break big molecules down into smaller, _______ ones
Digestive enzymes break big molecules down into smaller, soluble ones
Amalayse breaks down ______ into _______ and _____ ______. it is produced in the salivary ______, _____ intestine and ________
amalayse breaks down starch into maltose and other sugars. It is produced in the salivary glands, small intestine and pancreas
________ breaks down protein into _____ _____. It is produced in the _______, small _________ and ________
Protease breaks down protein into amino acids. It is produced in the stomach, small intestine and pancreas
______ breaks down _____ into glycerol and fatty acids. It is produced in the small intestine and ________
Lipase breaks down lipids into glycerol and fatty acids. It is produced in the small intestine and pancreas
Bile speeds up digestion in two ways. Give the two ways bile speeds up digestion.
- It makes conditions alkaline so enzymes in the small intestine work better
- It emulsifies fat so there’s a larger surface area for lipase to work on
Where is bile produced?
Bile is produced in the liver
Where is bile stored?
Bile is stored in the gall bladder.
