Unit 3 AOS 1 Flashcards
Process of catabolism
Breakdown of larger molecules
e.g. digestion of food
Process of anabolism
Synthesis of larger molecules
e.g. transcription/translation
What are cofactors
Inorganic ions
e.g. CA2+
What are coenzymes
Organic molecules
e.g. ATP, NADP, NADPH
What is ATP
Made up of adenine, ribose sugar and a triphosphate (3) known as loaded
Releases energy by breaking phosphate bond (only one phosphate is lost)
What is ADP
Made up of adenine, ribose sugar and a diphosphate (2) known as unloaded
End product of ATP
Factors affecting enzyme action
Temperature
pH
Enzyme concentration
Substrate concentration
Competitive and non-competitive inhibitors
What is a substrate
Anything that an enzyme will bind with
What does an enzyme do
Catalyses or speeds up the reaction of something
What is photosynthesis
The conversion of light energy into chemical energy
What is the by-product of photosynthesis
Oxygen (O2)
Purpose of chlorophyll
A photosynthetic pigment that catalyses the reaction and splits water
Where is chlorophyll found in prokaryotes
Cytoplasm
Where is chlorophyll found in eukaryotes
Chloroplasts
Is sunlight an input
No
