Development is a process that ensures good quality of life to all the people in terms of happiness, harmony and satisfaction of essential needs. It is related to improvement, progress and aspirations of people. This definition of development would benefit all the sections of society as it shows the basic need approach. It allows more people to make meaningful choices and the pre-condition for this is the fulfilment of basic needs like food, education, health and shelter.
The previous concepts of development that were based on only economic growth have not been beneficial for poor people and environment and have resulted in a wide gap between rich and poor and imbalanced ecology. Therefore, a definition that aims towards improving the quality of people's life would justify the essence of development.

Mitochondria produce ATP through process of cellular respiration—specifically, aerobic respiration, which requires oxygen. The citric acid cycle, or Krebs cycle, takes place in the mitochondria. This cycle involves the oxidation of pyruvate, which comes from glucose, to form the molecule acetyl-CoA. Acetyl-CoA is in turn oxidized and ATP is produced.
The citric acid cycle reduces nicotinamide adenine dinucleotide (NAD+) to NADH. NADH is then used in the process of oxidative phosphorylation, which also takes place in the mitochondria. Electrons from NADH travel through protein complexes that are embedded in the inner membrane of the mitochondria. This set of proteins is called an electron transport chain. Energy from the electron transport chain is then used to transport proteins back across the membrane, which power ATP synthase to form ATP.

The digestion of proteins begins in the stomach and is completed in the small intestine. The enzymes that act on proteins are known as proteases.
Digestion in the stomach: The digestive juice secreted in the gastric glands present on the stomach walls is called gastric juice. The main components of gastric juice are HCl, pepsinogen, and rennin. The food that enters the stomach becomes acidic on mixing with this gastric juice.
The acidic medium converts inactive pepsinogen into active pepsin. The active pepsin then converts proteins into proteases and peptides.
Proteins {tex}\begin{array}{l}\xrightarrow{Pep\sin}\\\end{array}{/tex} Proteoses + Peptides
The enzyme rennin plays an important role in the coagulation of milk.
Digestion in the small intestine: The food from the stomach is acted upon by three juices present in the small intestine – pancreatic juice and intestinal juice (known as succus entericus).
Action of pancreatic juice
Pancreatic juice contains a variety of inactive enzymes such as trypsinogen, chymotrypsinogen, and carboxypeptidases. The enzymes are present in an inactivated state. The enzyme enterokinase secreted by the intestinal mucosa activates trypsinogen into trypsin.
Trypsinogen{tex}\begin{array}{l}\xrightarrow{\;Enterokinase}\\\end{array}{/tex}Trypsin + Inactive peptide
The activated trypsin then activates the other enzymes of pancreatic juice.
Chymotrypsinogen is a proteolytic enzyme that breaks down proteins into peptides.
Chymotrypsinogen {tex}\begin{array}{l}\xrightarrow{Tryp\sin}\\\end{array}{/tex} Chymotrypsin
Proteins{tex}\begin{array}{l}\xrightarrow{Chymotryp\sin}\\\end{array}{/tex} Peptides
Carboxypeptidases act on the carboxyl end of the peptide chain and help in releasing the last amino acids.
Peptides{tex}\begin{array}{l}\xrightarrow{\;Carboxypeptidase}\\\end{array}{/tex}Smaller peptide chain + Amino acids
Action of bile juice
Bile juice has bile salts such as bilirubin and biliverdin which break down large, fat globules into smaller globules so that pancreatic enzymes can easily act on them. This process is known as emulsification of fats. Bile juice also makes the medium alkaline and activates lipase. Lipase then breaks down fats into diglycerides and monoglycerides.
Action of intestinal juice
Intestinal juice contains a variety of enzymes. Pancreatic amylase digests polysaccharides into disaccharides. Disaccharidases such as maltase, lactase, sucrase, etc., further digest the disaccharides.
The proteases hydrolyse peptides into dipeptides and finally into amino acids.
{tex}\begin{array}{l}\xrightarrow{dipeptides}\\\end{array}{/tex} Amino acids
Pancreatic lipase breaks down fats into diglycerides and monoglycerides.
The nucleases break down nucleic acids into nucleotides and nucleosides.
