Glencoe Biology Chapter 15: Evolution

7.5.2 Outline the difference between fibrous and globular proteins, with reference to two examples of each protein type. – fibrous proteins are strands/sheets whereas globular proteins are
rounded; fibrous proteins (usually) insoluble whereas globular proteins
(usually) soluble; globular more sensitive to changes in pH/temperature/salt than fibrous; fibrous proteins have structural roles / other specific role of
fibrous protein; globular proteins used for catalysis/transport/other specific role of globular protein; named fibrous proteins e.g. keratin/ fibrin/ collagen /actin /myosin / silk protein; named globular protein e.g. insulin/ immunoglobulin/ haemoglobin/named enzyme;
Gnathostomata – super-class of vertebrae including organisms with jaws.
milliliter – is 1/1000 part of a liter
*1,000 ml is the same as 1 liter
1,000 ml or 1,000 cm3 is the same as 1 liter
Explain why the Sun is vital to all ecosystems? – The sun supplies energy for all living organism. Autotrophs convert light energy into chemical energy and the chemical energy is used to form ATP (cell energy) for all metabolism in organisms.
coniferous – term used to refer to trees that produce seed bearing cones and have thin leaves shaped like needles
homozygous recessive – both alleles for a trait are the same and recessive (aa)
exoskeleton – A hard, external skeleton that protects an animal and provides points of attachment for muscles.
endocytosis moves large things in Exocytosis moves large things out – How do endocytosis and exocytosis differ?
enzymes – proteins that speed up an reaction
The hormone that stimulates the adrenal cortex is _____ hormone.
6.2.2 State that coronary arteries supply heart muscle with oxygen and nutrients – ◾The heart is a muscle that must continually contract in order to pump blood around the body
◾Coronary arteries form a network of vessels around the heart and supply the cardiac tissue with oxygen and nutrients (i.e. glucose)
◾These are required to produce the necessary energy via aerobic respiration – if a coronary artery is blocked, a heart attack may occur
transformation – process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria
topsoil – Soil that is made up of loam, humus, and living organisms.
cranium – The human skull consists of the ______________ and the bones of the face.
The hоrmоne thаt stimulаtes the аdrenal cоrtex is _____ hormone.
thymine (T) – A single-ring nitrogenous base found in DNA.
Quanitative/qualitative – Information with numbers/information describing something
Pyruvate – Substance produced by the breakdown of glucose in the cytoplasm in fermentation or during the first stage of aerobic respiration.
