General Biology Final Review

progestin – One of a family of steroid hormones, including progesterone, produced by the mammalian ovary. Progestins prepare the uterus for pregnancy.
habitat – An area that provides an organism with its basic needs for survival.
Phase 2: Light Independent Reactions – The Calvin Cycle – 6CO2 molecules combine with six 5-carbon compounds to form twelve 3-crabon molecules called 3-phosphoglycerate (3-PGA). This is called carbon fixation.
The energy in ATP and NADPH is transferred to the 3-PGA molecules to form high-energy molecules called glyceraldehyde 3-phosphates (G3P). ATP supplies the phosphate group for G3P molecules and NADPH supplies hydrogen ions and electrons.
Two G3P molecules leave the cycle to be used for the production of glucose and other organic compounds.
An enzyme (Rubisco) converts the remaining ten G3P molecules into 5-carbon molecules called ribulose 1, 5-biphosphate (RuBP). These molecules combine with CO2 to continue the cycle."
Reproduction – Can just be your cells making copies of themselves. It doesn't have mean having children
allopatric speciation – When a population is divided; leads to speciation.
antagonistic hormones – Two hormones that have opposite effects.
State of total deficient pituitary gland activity
Genes – The units of inheritance that transmit information from parents to offspring. Genes are grouped into longer molecules called chromosomes and control the activities of the cell.
Robert Hooke – English scientist that cut a thin slice of cork and looked at it under his microscope. To him, the cork seemed to be made up of empty little boxes, which he named cells.
Cirrhosis – A liver disorder brought on
by alcoholism and obesity
which results in fatty liver
tissue and fibrous scar
tissue that can lead to
liver failure
substrate – reactant in a chemical reaction upon which an enzyme acts
B2:Capillaries – Link the arteries and veins- walls only one-cell thick to allow transfer of substances to and from cells
Stаte оf tоtаl deficient pituitаry gland activity
Light-dependent reactions – the phase of photosynthesis in which sunlight is converted to chemical energy and oxygen is released
nasal cavity – The chamber into which air is drawn into, where it is filtered, warmed, and humidified before passing into the rest of the respiratory system.
