Q

What are the three main types of energy cells require

A

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.

Q

What is the structure of ATP?

A

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.

Q

How is ATP released?

A

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

Q

Is ATP a good long-term energy store

A

No, ATP is not a good long-term energy store fat and carbohydrates are much more efficient for this and are used.

Q

What is used to create ATP

A

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

Q

What are the properties of ATP

A

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
