Bisv Ib Biology Topic 7 Nucleic Acids And Proteins

photosynthesis – …process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water.
plasmids – Small rings of DNA found naturally in some bacterial cells in addition to the main bacterial chromosome. Can contain genes for antibiotic resistance, or other "contingency" functions.
Reproductive cell – Mainly refers to sperm and egg cells, or gametes. Also spores produced by some green plants, fungi, and some protists.
The parts of a virus – Protein coat (or viral envelope) & DNA or RNA (genome)
reproductive system – The body organ system responsible for reproduction.
BMR – (Basic Metabolic Rate) – The amount of energy needed to maintain essential body processes, such as heart pumping, breathing and maintaining a constant temperature.
what is homeostasis – stable internal enviornment
An instrument used to measure pressure within the eye and the diagnosis of glaucoma is a
synaptic vesicle – A membranous sac containing neurotransmitter molecules at the tip of the presynaptic axon.
Krebs cycle – Series of reactions in which pyruvate is broken down into carbon dioxide inside the mitochondria of cells; also called the tricarboxylic acid cycle and the citric acid cycle.
trans fat – an unsaturated fat containing one or more trans double bonds
Embryology – A branch of science that focuses on the study of the development of an embryo.
limiting factor – An environmental factor that prevents a population from increasing
Carbohydrate monomer – saccharide
mutation – a change or alteration in form or qualities
An instrument used tо meаsure pressure within the eye аnd the diаgnоsis оf glaucoma is a
electrogenic pump – transport protein that generates voltage across a membrane
ex/ sodium-potassium pump in animals (net transfer of one positive charge)
ribonucleic acid – a type of single-stranded nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); functions in protein synthesis, gene regulation, and as the genome of some viruses
valence – Electrons in the highest occupied energy level of an element's atoms; determines the chemical properties of an element. To find this amount look at an items group #. These are usually the only electrons involved in chemical bonds.
Tonsils – Lymphatic tissue at the
back of the mouth which
helps fight disease entering
the digestive system
Values – The behaviors, beliefs, and attitudes that are considered important by an individual or society. In science they can be a driving force for research, discourage particular kinds of research, or influence the manner in which research is conducted.
