Catabolic and Anabolic Reactions
Energy from catabolic reactions is used to combine ADP and a Pi to resynthesize ATP
ADP + Pi + energy ==> ATP
Energy is released to drive anabolic reactions
ATP ==> ADP + Pi + energy
When simple molecules are combined to form complex molecules (anabolism)
ATP provides the energy for synthesis, and again some energy is given off as heat
What is formed when the terminal phosphate group is split from ATP
Adenosine diphosphate (ADP)
Catabolism provides
Energy and building blocks for anabolism
Anabolism uses
Energy and building blocks to build large molecules
Catabolic reactions are generally
Hydrolytic reactions and they are exergonic
Metabolic pathways are determined by
It's enzymes
A cell's metabolic pathways are determined by
Its enzymes, which are in turn determined by the cell's genetic makeup
Catabolism releases energy by
Oxidation of molecules
Exergonic
Produces more energy than they consume
Hydlolytic reactions are
Reactions which use water and in which chemical bonds are broken
Catabolic reactions
Release energy
Anabolic reactions
Require energy
A metabolic pathways is
Sequences of chemical reactions
When complex molecules are split apart (catabolism)
Some of the energy is transferred to and trapped in ATP, and the rest is given off as heat
The energy for chemical reactions is
Stored in ATP
Anabolism uses energy to
Synthesize macro-molecules that make up the cell
Enzymes are determined (encoded) by
The cell's genetic makeup
Examples of anabolic processes are
The formation of proteins from amino acids, nucleic acids from nucleotides, and polysaccharides from simple sugars
Metabolism
The sum of all chemical reactions within a living organism
Example of catabolism
A cell break down sugars into carbon dioxide and water
Anabolism
A chemical reaction in which simpler substances are combined to form more complex molecules
Catabolism
A chemical reaction that results in the break-down of more complex organic molecules into simpler substances
A molecule of ATP consist of
An adenine, a ribosome, and three phosphate groups
Dehydration synthesis
Are reactions that release water
Anabolic processes often involve
Dehydration synthesis reactions and they are endergonic
The energy of catabolic reactions is
Used to drive anabolic reactions
