Answer Key  

1. Physiology is the study of the normal mechanical, physical and  biochemical processes of animals and plants  

2. Living things organize themselves using energy and raw materials from  their surroundings (metabolism), maintain integrity in the face of  disturbances (maintain homeostasis), and reproduce.  

3. Homeostasis – the ability to maintain integrity in the face of disturbances  4. Chemical, cellular, tissue, organ, body system, and organism level 5. 4 types of tissue – Epithelial, connective, muscular, and nervous  a. Epithelial - skin

Ribosomal RNA translates the mRNA code into  amino acid sequences. Transfer RNA transfers the appropriate amino acids from cytoplasm to ribosome to be added to the protein under  


14.Different genes are expressed in different tissues or at different times  through the regulation of individual genes with promoters and  

transcription factors.

23.The mitochondria is the power house of the cell.  

24.The nucleus controls the cell and all its functions. It also holds the DNA.  25.The electron transport chain also produces water.

26.The cell membrane is a phospholipid bilayer.  

27.Facilitated Diffusion  

28.The cell membrane is made up of phospholipids and proteins for transport  29.Integral proteins and Peripheral proteins  

30.Membrane permeability depends on size, force, and lipid solubility  31.The Endocrine system  

32.The rate at which diffusion occurs depends on Concentration gradient,  permeability, surface area, molecular weight, distance and temperature.  33.Electric charge

34.Osmosis is the movement of water across the membrane from an area of  low concentration to high concentration.

41.Paracrines, neurotransmitters, hormones, neurohormones, pheromones,  and cytokines

42.Binding of hormone to its receptor activates a G protein. The activated  alpha subunit links with adenylyl cyclase in the membrane. The activated  adenylyl cyclase converts intracellular ATP to cyclic AMP. Then the cyclic  AMP activates protein kinase A. The protein kinase A phosphorylates  intracellular proteins, leading to the cellular response.  

43.Most hormones are derived from protein.  

44. The A band  

45. Fast-oxidative  

46. Fast muscle fibers and slow muscle fibers are different in the speed at  which they contract, myosin-ATPase activity and their resistance to fatigue.  Fast has a lower resistance to fatigue, higher myosin-ATPase activity and  faster contraction time. Slow-oxidative fibers also have a lower glycogen  content that fast.

57. Cholesterol  

58. Hypertrophy – increase in size of myofibrils Hyperplasia – increase in  number of cells  

59. First and action potential arrives at the terminal which stimulates the  release of Acetylcholine. This diffuses across the cleft and triggers an action  potential in the muscle fiber. The action potential moves across the surface  membrane and into the fibers interior through the T-tubules. This triggers the  release of Calcium from the sarcoplasmic reticulum into the cytosol. Next  calcium binds to the troponin on the thin filaments. Calcium binding to  troponin causes tropomyosin to change shape, moving from its position  blocking the binding sites on the actin. Next the myosin cross bridges attach  to actin at the now exposed binding sites. The binding triggers the cross  bridge to bend, pulling the thin filament over the thick filament toward the  center of the sarcomere. This power stroke is powered by energy provided by  ATP. After the power stroke the cross bridge detaches from actin. If calcium is  still present then the cycle starts again with the power stroke. When the  action potentials stop, calcium is taken up into the sarcoplasmic reticulum.  Without the presence of calcium, tropomyosin moves back over the myosin  binding sites on the actin. This causes the contraction to stop and the thin  filaments slide back to their relaxed positions.
