Biology Chapter 9 Cell Respiration

rough endoplasmic reticulum – That portion of the endoplasmic reticulum with ribosomes attatched that make membrane proteins and secretory proteins.
Cytoplasm – a jellylike fluid inside the cell in which the organelles are suspended
cyclin-dependent kinases – a protein kinase only active when attached to a particular cyclin
Food pyramid – a hierarchy of food chains with the principle predator at the top. Shows that energy, and most often, biomass and numbers decrease as you go up the food chain
R-selection – an opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.
ecosystems – A specific biological community and its physical environment interacting in an exchange of matter and energy.

9.1 – when oxygen not present, release energy from food molecules by producing ATP in absence of oxygen

pH – The measure of acidity or alkalinity (basicity) of an aqueous solution scaling from 1 (highly acidic)to 14 (highly alkaline) with amid point of 7 (neutral).
The suffix -ary is defined as
Cell Wall – strong, rigid and made of cellulose
Hypothesis – – an explanation for a question or a problem that can be formally tested.
genetic linkage – tendency for genes located close together on the same chromosome to be inherited together.
Evolution – Gradual change in a species through adaptations over time.
Mitochondria – The organelle that is the site of aerobic respiration in eukaryotic cells
ribosome – the site of protein synthesis (where proteins are made)
The suffix -аry is defined аs
nitric oxide (NO) – Local regulator that regulates blood oxygen levels, A gas produced by many types of cells that functions as a local regulator and as a neurotransmitter.
genomes – the genetic information (DNA) of an organism
nucleus – control center of the cell and contains RNA and DNA
Cell theory – the theory that (1) all organisms are composed of one or more cells, (2) the cell is the basic unit of structure and organization of organisms, (3) all cells come for pre-existing cells.
