A cofactor is a non-protein chemical that assists with a biological chemical reaction. Nucleotide with two phosphate groups that can accept another phosphate group and become ATP. Molecule definition is - the smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms. Because the anions are such a large group of ions, they may be further divided according to type. During cellular respiration, NADH carries electrons to the electron transport chain in mitochondria. NADP+ (nicotinamide adenine dinucelotide phosphate) (p. 112). Transport proteins are proteins that transport substances across biological membranes. Most pumps use metabolic energy (ATP) to function. If there are only a few ions in a solution, will it conduct a strong or weak electric current? Sodium ions along with the potassium ions are involved in the conduction of nerve impulses in our body. Therefore, isomers contain the same number of atoms for ea 3. Measurement. An anion is an ion that carries a net negative electrical charges. Almost all enzymes are proteins, made up of chains of amino acids, and they perform the critical task of lowering the activation energies of chemical reactions inside the cell. An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge.In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.

Plasma, also called blood plasma, the liquid portion of blood.Plasma serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.It is also a transport system for blood cells, and it plays a critical role in maintaining normal blood pressure. Substance that participates in a reaction. Energy that must be added in order for molecules to react with one another. A type of kinetic energy, such as walking or running. Glycolysis takes place in the cytoplasm of most prokaryotic and all eukaryotic cells. Study Flashcards On Biology off of Quizlet at Cram.com. How to use molecule in a sentence. How to use molecule in a sentence. Reactant in a reaction controlled by an enzyme. For most animal cells potassium ions (K +) are the most important for the resting potential. It you believe this, you're not exactly wrong. It may just be the similar 'oxic' sound, but to many, 'hydroxide' sounds like a toxic compound. Isomers are important in biological systems because: A. Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Equilibrium potentials. Facilitated diffusion is a form of facilitated transport involving the passive movement of molecules along their concentration gradient, guided by the presence of another molecule – usually an integral membrane protein forming a pore or channel.. Ion definition, an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion ), which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion ), which is created by an electron gain and is attracted to the anode. morphē = Form, Gestalt; Adj.
