GCU BIO 201 EXAM 1 WITH WELL DETAILED SOLUTIONS – GRADED A+
Pinocytosis
Cell drinking
Phagocytosis
Cell eating
Exocytosis
release of substances outside a cell by the fusion of a vesicle with the membrane.
Endocytosis
process by which a cell takes material into the cell by infolding of the cell membrane
osmosis
Low to High, Diffusion of water through a selectively permeable membrane
Diffusion
Movement of molecules from an area of higher concentration to an area of lower
concentration.
,tonicity
the ability of a surrounding solution to cause a cell to gain or lose water
isotonic solution
when the concentration of two solutions is the same (moving in and out equally)
Cori Cycle
Krebs cycle
What is the purpose of the Cori Cycle (Lactic acid cycle)?
If the body runs out of oxygen the body can stay alive and functioning for a few more
minutes.
The Krebs cycle produces what?
CO2, NADH, FADH2 that carry energy to the second part of cellular respiration
What is Oxygen's role in the electron transport chain?
To stabilize H ions
Cellular Respiration steps and how much ATP each one produces
, 1. Glycolysis (NET 2)
2. Krebs Cycle (Net 2)
3. Electron Transport Chain (Net 32)
Total 36 ATPs
Glycolysis
first step in releasing the energy of glucose, in which a molecule of glucose is broken into
two molecules of Pyruvate's
Krebs cycle
second stage of cellular respiration, in which pyruvic acid is broken down into carbon
dioxide in a series of energy-extracting reactions
Electron Transport Chain
a series of proteins in which the high-energy electrons from the Krebs cycle are used to
convert ADP into ATP
Anatomy and Physiology
