Metabolic Pathways Flashcards
Cell metabolism
The collective term for thousands of biochemical reactions that occur within a living cell
Catabolic pathways
Breakdown of complex molecules to simple molecules
Releases energy
Anabolic pathways
biosynthesis of molecules from simple to complex
Requires energy
What is a metabolite?
A chemical substance that can react
Found within a cell
Is temporary as it is a stage towards the end product
Features of a metabolic pathway
They have reversible and irreversible steps and alternative routes
Some metabolic pathway is can bypass steps on a pathway
What a metabolic pathway is controlled by?
The product or action of particular enzymes in the pathway
The regulation of the rate of reaction of key enzymes within the pathway
What are selectively permeable membrane is made from?
Phospholipids and proteins
What do membranes form and why?
Membranes form surfaces and compartments for metabolic pathways to allow high concentrations and high reaction rates
What are proteins in the cell membrane used for?
Cell communication
Channel forming proteins
