There are four biological marcomolecules essential to the function of a cell: lipids‚ proteins‚ carbohydrates and nucleic acids. Proteins are made up of amino acids that have a carbon in the center of the structure with four chemical groups attached to the sides. Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis

feminine traits or the lack thereof as male or female. We can delve into this complex concept and break the ambiguity of it by examining three theories which are biological‚ interpersonal‚ and psychological in scope. This paper will explain each theory and will offer my views on them as well. The biological theory of gender teaches that “biological characteristics are the basis of gender differences” (Wood 41). This theory presumes that “x and y chromosomes‚ hormonal activities‚ and brain specialization

Biological theories of crime causation adhere to the principle that many behavioral predispositions‚ including aggression and criminality are constitutionally or physiologically influenced and inherited of the first basic principles of biological theories is the mind and locus of personality which is the organ brain. The brain is the organ of behavior. We have the basic determinants of human behavior passed on from generation to generation. Human behavior and traits are genetically based to a considerable

Describe the development of gender as explained by the biological approach and compare it to the psychodynamic and learning explanation of gender development (12 Marks) The Biological approach states that gender development arises from biological processes. Gender differences are seen as resulting from sex differences. In other words‚ women and men act‚ think and feel differently because of differences in how their brains work. These brain differences result from chromosomal differences and hormonal

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

ROLE OF NEUROTRANSMITTERS IN LEARNING AND MEMORY – Martinez and Kesner (1991) Aim: determining the role of the neurotransmitter acetylcholine on memory Method: * Rats were trained to go through a maze and get to the end‚ where they received food * Researcher injected one group of rats with scopolamine (blocks acetylcholine receptor sites thus decreasing available acetylcholine) * Injected second group of rats with physostigmine (blocks the production of cholinesterase – cholinesterase

This discussion will also include major subtypes of molecules. The four Major biological molecules are Carbohydrates‚ Lipids‚ Proteins‚ nucleic acids. Carb is an abbreviation for carbohydrates. The body breaks down carbohydrates into simple sugars. Carbohydrates are easily used for energy by the body. The nervous system and brain

Discuss two biological explanations of depression (8+16 marks) AO1: One biological explanation for depression is family studies. Family studies have proved that having a first-degree relative with depression appears to be a risk factor of depression. These studies select people who already have the depression (the probands) and examine whether other members of their family have been‚ or might be diagnosed with depression. Research has found that around 20% of such relatives have depression compared
