1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet
