Mr McAlonan - ATP Energy Flashcards
What biological processes require energy.
Muscle contractions, cell division, the transmission of nerve impulses, and even memory formation uses energy
What are the three main types of energy cells require
Synthesis e.g. moving Large molecules such as proteins. Transport e.g. moving molecules and ions across a cell membrane by active transport. Movement e.g. protein fibres in muscle cells causing muscle contractions.
What does an ATP molecule consists of
And ATP molecule is composed of a nitrogen base a pentose sugar and three phosphate groups it’s a nucleotide.
What is the structure of ATP?
The structure of ATP is similar to a structure of DNA and RNA however the base in ATP is always Adilene and three phosphate groups instead of one the sugar in ATP is ribose and in RNA nucleotides.
How is ATP released?
ATP is released by the phosphate bond being broken this then leads to a large amount of energy released more energy released then is used to break the phosphate bond
What is the equation for the release of energy
ATP + H2O —> ADP + Pi + energy
How does the hydrolysis of ATP happen
The hydrolysis of ATP does not have an isolation but in association with the energy requiring reactions they happen simultaneously
Is ATP a good long-term energy store
No, ATP is not a good long-term energy store fat and carbohydrates are much more efficient for this and are used.
What is used to create ATP
ATP is created by cellular respiration. This occurs by attaching a phosphate group onto an ADP molecule this is called phosphorylation water is removed in this process another example of this is a condensation reaction
What are the properties of ATP
And ATP molecule is ideal for energy transfer. It’s small and was easily into and out of cells. It is water soluble and requiring a process of an aqueous environment. The bonds between the phospholipids is enough for cellular reaction and not to light the energy is wasted. It releases energy in small quantities suitable for cellular needs and is easily generated can be recharged with energy
