Metabolism - ANSWER ✔✔All of the chemical reactions of the body
Anabolism - ANSWER ✔✔Energy-storing (endergonic) synthesis
reactions
•Requires energy input
Catabolism - ANSWER ✔✔Energy-releasing (exergonic)
decomposition reactions
•Breaks covalent bonds
•Produces smaller molecules
,Mitosis - ANSWER ✔✔Mitosis is a type of cell division in which one
cell (the mother) divides to produce two new cells (the daughters) that
are genetically identical to itself.
Meiosis - ANSWER ✔✔a type of cell division that results in four
daughter cells each with half the number of chromosomes of the parent
cell
Compare and contrast mitosis and meiosis - ANSWER ✔✔-Both
involved in cell division resulting in new cells.
-mitosis produces cells that are genetically identical to the parent cell
and the nucleus divides once.
-Meiosis produces cells that have ½ the number of chromosomes from
each parent cell and the nucleus divides twice.
crossing over - ANSWER ✔✔-The sharing of genetic material
between two non-sister chromatids in a homologous pair.
-occurs during prophase I of meiosis before tetrads are aligned along the
equator in metaphase I.
-occurs when chromosomal homologs exchange information during
metaphase of Meiosis I
, Nucleus - ANSWER ✔✔Controls cell because it contains DNA, the
genetic code--instructions for making proteins, which in turn determine
cell structure and function
Endoplasmic Reticulum - ANSWER ✔✔-Network of connecting sacs
and canals
-Carry substances through fluid cytoplasm
-Two types: rough and smooth
Rough ER - ANSWER ✔✔collects, folds, and transports proteins
made by ribosomes, has ribosomes on it
Smooth ER - ANSWER ✔✔synthesizes chemicals, produces lipids
that makes up new membrane
Mitochondria - ANSWER ✔✔-Powerhouse of the cell
-ATP is created in mitochondria
-Involved with energy-releasing chemical reactions
-Contains one DNA molecule
Lysosomes - ANSWER ✔✔-Contains digestive enzymes that digest
and break down things
