ATP Flashcards
What can energy be defined as
The ability to do work
The three types of producers that can produce energy
- plants
- algae
- phytoplankton
What does ATP stand for
Adenine triphosphate
Is photosynthesis endothermic or exothermic
Endothermic
ATP is made of
- adenine
- ribose
- 3 phosphate groups
Bond breaking releases
Energy
Hydrolysis of ATP -> ADP (diphosphate) is catalysed by
the enzyme ATPase
ATP can be formed from ADP + Pi in how many ways
3
What are the 3 ways ATP can be formed
- Photophosphorylation (occurs in the chlorophyll during photosynthesis)
- Oxidative photophosphorylation - occurs in the mitochondria during electron transport chain (part of respiration)
- Substrate level photophosphorylation- when phosphate groups are transferred from donor molecules to ADP
ATP advantages
- instant source of energy in the cell
- Releases energy in small amounts as needed
- It is mobile and transports chemical energy to where it is needed in the cell
- Universal energy carrier and can be used in many different chemical reactions
Photosynthesis is split into what 2 processes
Light dependent and not light dependent (the Calvin cycle)
the structure of ADP and ATP as phosphorylated nucleotides
Comprising a pentose sugar (ribose), a nitrogenous base (adenine) and inorganic phosphates
(ADP = 2, ATP = 3)
