What is metabolism? |
Metabolism is a series of enzyme-catalyses reactions that provide energy for life processes. |
|
|
What makes carbon special in the field of molecular biology? |
Carbon is important because of its ability to readily form tetrahedral covalent bonds around it to form a variety of stable molecules which are essential for life. |
|
|
Give 4 important molecules made up of carbon. |
Carbohydrates Proteins Lipids Nucleic acids |
|
|
What are the two types of metabolism? |
Anabolism Catabolism |
|
|
Explain anabolism |
The synthesis of complex molecules from simple molecules through condensation reaction. |
|
|
Explain catabolism |
The breakdown of complex molecules into simpler molecules through hydrolysis reactions. |
|
|
What is a condensation reaction? |
A reaction in which two molecules are combined, which the loss of a water molecule. |
|
|
Explain hydrolysis reaction |
A reaction in which a larger molecule is broken down to two (or more) molecules, consuming water as a reactant |
|
|
What is a metabolic pathway? |
A metabolic pathway is a series of metabolic reactions that produce a particular product. |
|
|
Explain end-product inhibition. |
End product inhibition refers to a mechanism of metabolic pathways in which the final product acts a non competitive inhibitor for the first enzyme of the pathway, inhibiting the pathway from working. |
|
|
Give three examples of cycle metabolic pathways. |
Kreb’s cycle Calvin’s cycle Ornithin’s cycle |
