Cell Transport The movement of molecules can be either passive (no energy) or active (needs energy) depending upon the membrane structure and concentration.

Presentation transcript:

(3) Contractile proteins of muscle are mostly _fibrous_ proteins. (1) When a cell is resting, there’s more _K+_ inside and more _Na+_ outside the cell. (2) What is the nitrogenous base that is different between DNA and RNA? DNA–T/ RNA–U (3) Contractile proteins of muscle are mostly _fibrous_ proteins. (4) T or F: A low blood pH is an indication of respiratory alkalosis. (5) What is the air exchanged during normal breathing? Tidal volume (6) Carbon dioxide causes the blood to become _acidic_. (7) Name a few substances that will and will not diffuse through the cell membrane. (8) _Sarcomere_ is the functional unit of a skeletal muscle. (9) Which phase of deglutition (swallowing) is voluntary? Buccal (10) When a neuron reacts to a stimulus, the membrane potential changes and is called an _action potential_. (11) Enteroendocrine__ cells secrete gastric hormones. (12) Aldosterone aids in sodium reabsorption, which conserves _water_. (13) The fluid only found inside cells is called _intracellular__. (14) Your sour tastes are initiated by an influx of _H+ ions_. (15) A decrease in airway resistance is a result of (dilated/contracted) airways. (16) Negative feedback mechanisms work to prevent _sudden severe changes in the body_. (17) The rate limiting step of neural transmission is _the synapse_. (18) Glucose is a __monomer__ of glycogen. (19) What is the movement of nutrients from the GI tract to the blood or lymph? Absorption (20) When blood glucose levels rise, _insulin_ is released. (21) In skeletal muscles, __Ca++__ binds to troponin, moving tropomyosin. (22) Which nervous system inhibits salivation, causing dry mouth? Sympathetic NS (23) The movement of ions against their concentration gradients is _active_ transport. (24) What are the cells in your eye that detect dim light? Rods (25) What begins to denature in the stomach? Protein
