digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down into small molecules that can then be absorbed

Properties of life‚ Basic Chemical Terminology‚ Molecules and Compound of a cell Properties of life: All living things are made of cells and keep certain characteristics in common. All living things are divided into several characteristics: order‚ reproduction‚ growth and development‚ energy processing‚ respond to the environment‚ regulation and evolution. Cells are either made of prokaryotic or eukaryotic. Prokaryotic is simple‚ small and lacking membrane-enclosed membrane. Eukaryotic

The organic compounds are carbohydrates‚ lipids‚ nucleic acids‚ and proteins. Each which are made up of elements and monomers. Each organic compound has it’s own function and chemical structure. Each compound also plays a role in living organisms. Carbohydrates are composed of several elements‚ and one monomer. The elements include: carbon‚ hydrogen‚ and oxygen atoms. Carbohydrates are composed of only one monomer‚ which is monosaccharides. Monosaccharides are the simplest carbohydrates‚ and

The effect of drugs‚ toxins‚ and other molecules on synapse and synapse transmission. The synapse is the small gap separating two neurons‚ the presynaptic neuron (neuron that carries the impulse to the synapse‚) and postsynaptic neuron (neuron that carries the impulse away from the synapse.) It separates the axon terminals of the presynaptic neuron from the postsynaptic neuron. The synapse is made of three major parts: a presynaptic neuron‚ a postsynaptic neuron‚ and a synaptic cleft. The presynaptic

3) What does sodium chloride represent? Sodium chloride represents the two atoms that when put together create a molecule NaCl 4) Explain the concept of an ionic bond. An ionic bond happens when two or more ions bond together because of their opposite charge. They are drawn to each other like magnets because of their opposite charge. 5) Why does the compound sodium

Unit 10: Biological Molecules and Metabolic Pathways C: Explore the factors that can affect the pathways and the rate of photosynthesis in plants The following report is about the factors which can affect the pathways and the the rate of photosynthesis in plants. This report will cover what photosynthesis is ‚ the factors which may affect photosynthesis in working poorly‚ light independant and dependant reaction. An investigation will be carried out which will include the factors that affect photosynthesis

Neuroscience: Neurotransmitters (small molecule and neuroactive)‚ storage release removal and disease. 1. The brain is made up of neurons that process and transmit information by electrochemical signaling. Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of

Analysis: The purpose of this lab is to find out how does the concentration of a saline solution affect the movement of the solvent molecules. Before the experiment‚ it was predicted that the saline solution in baggies would remain inside‚ without mixing with the water‚ and that the mass would not change. Throughout the experiment‚ the saline solution was added into the baggie‚ it was discovered that a small portion of the saline solution would leave the bag. In the baggie that has 0.2 percent
