Biol 436 Exam 1 Questions and Verified
Answers
NaKATP Pump ✅Work the exact same in every tissue they are found in, however
functions can be different which aids in prediction, symporter; 3 Na leave cell and 2 K
go into cell

Physiology ✅Study of how the body works to maintain life

Life ✅Ability of a cell to do biochemistry; acquire, store, and use energy; and get rid of
waste products

Reproductive System ✅Doesn't play a role in immediate life, but is important for off-
spring

Pathophysiology ✅Helps us understand normal physiology

Health ✅What is going on in the body to help it maintain life

Chronic Illness ✅Life long

Diabetes Melitis ✅Led to the discovery of the hormone insulin, Symptoms: get skinny
quickly while eating, drinking, and urinating frequently; if nothing is done the patient dies
within 2 weeks

Water ✅Basis of life, where biochemistry occurs

House Keeping Functions ✅Basic functions that all cells have

Specialized Functions ✅Functions of cells based on specific organ systems

Body Fluid Compartments ✅Intracellular and extracellular fluid compartments
separated by the plasma membrane/plasmalema

Extracellular Fluid ✅Outside of the cell, blood plasma and interstitial fluid

Intracellular Fluid ✅Where biochemistry is done

, Interstitial Fluid ✅80% of extracellular fluid exchange nutrients, energy molecules, and
remove waste products

Disadvantage of Single Cell Organisms ✅Cell is trapped in place

Body Systems ✅Control aspects of homeostasis

Homeostasis ✅Maintains constant internal environment/conditions

Set Points ✅Maintain temperature, pH, and glucose in fluids

Homeostatic Set Points ✅Are dynamic

Negative Feedback Loop ✅Negates deviations and brings them back to set points

Sensor of Negative Feedback Loop ✅Detects Deviation from set point, usually a
receptor in the nervous system

Integrating Center of Negative Feedback Loop ✅CNS/brain take information and
decide what needs to be done, sometimes handled locally

Effector of Negative Feedback Loop ✅Produces a response to get back to
homeostasis

Overshoot ✅Feedback that is too high and needs to come back down

Examples of Negative Feedback Mechanisms ✅Shivering and sweating

Integumentary System ✅Skin

Skeletal and Muscle Systems ✅Movement

Nervous and Endocrine Systems ✅Oversee homeostasis maintenance and integrate
other systems to make corrections

Cardiovascular and Lymphatic Systems ✅Circulate nutrients towards and waste
products away from cells

Respiratory Systems ✅Gas exchange of oxygen to generate ATP(energy source) and
CO2

Digestive System ✅Brings in more biomolecules (energy reserves)
