Function of proteins Flashcards
Carrier molecules
Beauty transport small molecules in. G. Haemoglobin found a rabbit in redbud cells by stocks to molecules and transport around the body
Hormones
You see Kay Mrs anybody a. G. Incheon is a hormone release of the body by the pancreas to regulate blood sugar levels.
Structural proteins
Structural proteins are physically strong. Collagen is a structural protein that strengthens connective-tissue like ligaments and cartilage
Reactions inside cells
Cells have thousands of different chemical reactions going on at the same time. These reactions need to be carefully controlled full stop you can you can make a reaction happen more quickly by raising the temperature, this would speed up the useful reactions and also the unwonted ones to . There is also a limit to how far you can raise temperature inside a living creature before it starts getting damaged
What acts as a biological catalyst
Living things produce enzymes which act as biological catalysts. I catalases substance that speeds up a reaction without being changed or used up in the reaction itself
What codes for an enzyme
Each enzyme is coded for by different gene, and has a unique shape which it needs to is job
What did Chemical reactions involve
Chemical reactions usually involve things either being split apart or joined together
What is the substrate
The substrate is the molecule angel in the react
What is an active site
Every enzyme has an active site – the part where it joins onto the substrate to catalys the reaction
Why do enzymes only work with one substrate
This is because , The enzyme to work, the substrate has to fit into the active site. If the substrate shape does not match the active site shap, Then a reaction will be capitalised. This is called the lock and key mechanism, because it’s a substrates fit into the enzymes justly key it into a lock
