The Importance Of Nitrogen Containing Compounds In Biology A Level - Essay (A*)

The importance of nitrogen containing compounds in biology A level - essay (A*)How is ATP used?>>> - Cell can't get energy directly from GLUCOSE.- In respiration: energy released from glucose is used to make ATP.- Condensation between Pi and ADP, using energy from energy-releasing reaction.- ATP synthase catalyses.- ATP diffuses to where energy is needed, hydrolysed here back into ADP and Pi, chemical energy released from phosphate bond and used - ATP HYDROLASE catalyses this.ADP and Pi recycled, process again.Properties of ATP>>> - Stores or releases only SMALL amount of energy at a time, no energy wasted as heat.- Easily broken down, energy can be released instantaneously.- CAN BE quickly re-made.- Can make other mol. more reactive by transferring one of phosphate groups (PHOSPHORYLATION)- ATP can't pass out of cell, always immediate source of energyCoenzymes>>> - Molecule that aids function of an enzyme- Transfer chemical group from one to another- NADP in photosynthesisTRANSFERS hydrogen from one to another, so can reduce and oxidise a moleculeChloroplasts>>> - Double membrane,- Thylakoids stacked up, forming grana, linked together by LAMELLAE.- Contain photosynthetic pigments, e.g. a, b, carotene.- Coloured substances, absorb light energy.Pigments found in thylakoid membranes - attached to
