Why do we need Energy?
· Active Transport moving ions and molecules
against a concentration gradient.
· Secretion moving large molecules out of cells
· Endocytosis bulk movement of large molecules
· Synthesis of large molecules from smaller ones
· Replication of DNA and cell organelles
· Movement of cilia, flagella and muscle
The Role of ATP
· It consists of adenine, ribose sugar and 3
· It can be hydrolysed to ADP and P, which
· The energy is therefore available in small,
· ATP is known as the universal energy
·Organic, non protein.
·It is made up nicotinamide, 2 ribose sugars,
adenine, and two phosphate groups.
·It can accept 2 hydrogen atoms.
·Made up of Pantothenic acid, adenosine, 3
phosphate groups and cysteine.
·It carries acetate from the link reaction to the Krebs
Glycolysis Part 1
Glucose (6C) · Glycolysis takes place in the
cytoplasm of all living cells.
· An ATP is hydrolysed and the
P phosphate group released is attached
Glucose-6-Phosphate on to the glucose molecule at carbon
· Glucose-6-phosphate changes to
· Another ATP molecule is hydrolysed
Fructose-6-Phosphate and Fructose-1,6-Bisphosphate is
P · The energy released from the ATP
activates the hexose sugar and
Hexose-1,6- prevents it being transported out the
· It is referred to as Hexose-1,6-
