Dive Biology Terms Lesson 23

triglyceride – three fatty acids and a glycerol (building blocks of lipids)
neuron – A nerve cell; the basic building block of the nervous system.
Lactic Acid Fermentation – Enzymes convert 2 pyruvate to 2 lactic acid. This requires energy from NADH, which then replenishes NAD+ for use in glycolysis.
controlled experiment – An experiment in which an experimental group is compared with a control group that varies only in the factor being tested.
What is a chromatid? – A chromatid is one half of a replicated chromosome. Sister chromatids are attached by the centromere.
Correctly sequence the following structures of the respiratory tract:
Alveoli, trachea, larynx, nares, pharynx, bronchi, bronchioles – nares, pharynx, larynx, tracea, bronchi, bronchioles, alveoli
Osmosis – – diffusion of water across a membrane
ectoplasm – the thin, watery cytoplasm near the plasma membrane of some cells
diffusion- – transport straight through the membrane
This organ system is responsible for immunity is the _________.
dalton – measure of mass for atoms and subatomic particles, same as amu
operon – a group of genes operating together to turn a gene "on" or "off" in bacteria 12-5
evolution – Change in organisms over time; process by which modern organisms have descended from ancient organisms.
This оrgаn system is respоnsible fоr immunity is the _________.
oxidative phosphorylation – When energy is released at each step of the chain is stored in a form the mitochondrion can use to make ATP.
solute – a substance dissolved in the solvent
How is a cell's DNA like the books in a library?
10.1 – A cell's DNA is a "genetic" library – the information that controls a cell's function is stored in the DNA.
Secondary Structure – The second level of protein structure; the regular local patterns of coils or folds of a polypeptide chain.
Osmotic Pressure – the external pressure that must be applied to stop osmosis
