We have indeed created man in the best shape (Holy Quran) Lecture # 1 Biochemistry Foundation Module November-2010

Aims of Medical Sciences ,[object Object],[object Object],[object Object],[object Object],[object Object]

What life means to a Biologist? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Cells are made up of Specific Chemical Compounds ,[object Object]

An uncountable variety of chemical compounds are related to life, e.g., Bacteria may contain over 5000 varieties. ,[object Object],[object Object],[object Object],[object Object],[object Object]

Growth and Reproduction are based on Chemical Compounds and Reactions ,[object Object],[object Object],[object Object],[object Object],[object Object]

Biological Concept of Life ,[object Object],[object Object],[object Object]

Basis of Health - Disease - Death ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Aim of studying Biochemistry? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Hundreds of planned chemical reactions are involved in life process ,[object Object],[object Object]

A Chemical Reaction Taking Place In Living Cell is Called Metabolic Reaction. ,[object Object],[object Object],[object Object]

Anabolic Reactions build up the tissues ,[object Object],[object Object],[object Object],[object Object]

Catabolic Reactions generate energy ,[object Object],[object Object],[object Object]

In a living cell both Anabolic and Catabolic reactions take place simultaneously according to the requirements and demands ,[object Object],[object Object],[object Object]

During life time balance of Anabolism and Catabolism shifts according to circumstances ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Energy is fundamental requirement of living systems ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Energy can be produced by actual burning of organic substances in air (Oxidation or Combustion). ,[object Object],[object Object],[object Object],[object Object]

In living system energy is generated by precise chemical methods ,[object Object],[object Object],[object Object],[object Object]

Bioenergetics (Biochemical thermodynamics) ,[object Object],[object Object]

Sources of Energy In Human cells ,[object Object],[object Object],[object Object],[object Object],[object Object]

Storage of energy in living system ,[object Object],[object Object],[object Object]

Adenosine Triphosphate (ATP) is the most commonly used Energy Storing Molecule Adenine | Ribose_______P Adenosine Monophosphate ~ P ~ P High Energy Phosphate Bonds

Capture of Energy as ATP Adenine | Ribose_______P ~ P ~ P Energy generated by oxidation of food stuffs is utilized for the formation of High- energy phosphate bonds. ADP is converted to ATP

Release of energy by ATP Adenine | Ribose_______P ~ P ~ P Hydrolysis of terminal  Generates 7300 Calories. ATP is Converted to ADP

Release of energy by ATP ,[object Object],[object Object],[object Object]

Release of energy by ATP Adenine | Ribose_______P ~ P + Pi Energy generated is utilized for: 1. Metabolic Reactions. 2. Muscle Contraction. 3. Heat.

An Overview of Energy Storage Adenine | Ribose__P Adenosine Monophosphate Adenine | Ribose__P __P Adenosine Diphosphate Adenine | Ribose__P __P __P Adenosine Triphosphate Catabolism of Nutrients CO2 + H2O Energy

Organic molecules (Nutrients Such as Glucose & Fats) contain energy, stored in their molecular structure ,[object Object],[object Object],[object Object],[object Object]

Generation and utilization of energy in human tissues is an important concern in medical science ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Cellular Respiration is the Main Source of Energy ,[object Object],[object Object]

ATP / ADP Cycle Adenine | Ribose — P ~  ~  ATP Adenine | Ribose — P ~  ADP 7300 cal/mol
