enzymes - --ANS---biological catalysts, usually proteins
fatty acids - --ANS---part of the structure of a lipid molecule
glycerol - --ANS---part of the structure of a lipid molecule
lipase - --ANS---enzymes that speed up the breakdown of lipids into fatty acids and glycerol
lipids - --ANS---include fats and oils and are found in foods such as butter, olive oil, and crisps.
They are made of carbon, hydrogen and oxygen
organ - --ANS---an aggregation (collection ) of different tissues working together to carry out
specific functions
,2|Page
organ system - --ANS---a group of organs that work together to carry out specific functions and
form organisms
proteases - --ANS---enzymes that speed up the breakdown of proteins into amino acids
proteins - --ANS---molecules that contain carbon, hydrogen, oxygen, and nitrogen and are made
of long chains of amino acids. They are used for building the cells and tissues of the body and to
form enzymes
simple sugars - --ANS---small carbohydrate units, for example glucose
tissue - --ANS---a group of specialised cells with a similar structure and function
adult stem cells - --ANS---stem cells that are found in adults that can differentiate and form a
limited number of cells
cell cycle - --ANS---the three-stage process of cell division in a body cell that involves mitosis
and results in the formation of two identical daughter cells
cloning - --ANS---the production of identical offspring by asexual reproduction
differentiate - --ANS---the process where cells become specialised for a particular function
, 3|Page
embryonic stem cells - --ANS---stem cells from an early embryo that can differentiate to form
the specialised cells of the body
mitosis - --ANS---part of the cell cycle where one set of new chromosomes is pulled to each end
of the cell forming two identical nuclei during cell division
stem cells - --ANS---undifferentiated cells with the potential to form a wide variety of different
cell types
therapeutic cloning - --ANS---a process where an embryo is produced that is genetically identical
to the patient so the cells can then be used in medical treatments
How many chromosomes in the human genome? - --ANS---23 pairs
Where are stem cells found in plants? - --ANS---Meristems in roots and stems
benign tumours - --ANS---growths of abnormal cells that are contained in one area, usually
within a membrane, and do not invade other tissues
cancer - --ANS---the common name for a malignant tumour, formed as a result of changes in
cells that lead to uncontrolled growth and division
