biological macromolecules – A group of biomacromolecules that interact with biologicalsystems and their environments
WHY IS DNA IMPORTANT FOR METABOLIC ACTIVITIES OF THE CELL – IT CONTROLS THE SYNTHESIS OF ENZYMES
Emergent properties – New properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases.
complement system – A group of about 30 blood proteins that may amplify the inflammatory response, enhance phagocytosis, or directly lyse extracellular pathogens.
Phagocytosis – The process by which a cell engulfs foreign substances or other cells
Series of chemical reactions where pyruvic acid is broken down into carbon dioxide – Krebs Cycle
signal transduction – one of the six major protein functions in the membrane; occurs when an external messenger fits and causes the protein to change shape and relay a message into the inside of the cell
Alleles – Different forms of a gene which occupy the same relative positions on a pair of homologous chromosomes.
Niche – Role or position a species has in its environment; includes all biotic and abiotic interactions as an animal meets its needs for survival and reproduction.
A fissure is defined as a
substrate-level phosphorylation – When an enzyme transfers a phosphate group from a substrate molecule.
glycogen – An extensively branched glucose storage polysaccharides found in liver and muscle cells; the animal equivalent of starch.
Stimulus – It is the thing that cause a reaction
Anaphase – Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell.
amniotic egg – An egg in which the embryo is protected by a hard or leathery shell.
A fissure is defined аs а
trophic level – An organism's position in the food chain.
glycoproteins – membrane carbohydrates that are covalently bonded to proteins
Metabolism – All of the chemical processes that happen in an organism.
