From our Eq. 4, an increase in pressure will typically occur due to a decrease in the system's volume - Equation 4: PV = nRT In our Eq. 1, ATP can be either a product or reactant - Equation 1: ATP ←→ ADP + Pi + energy Our Eq. 3 in the rightward direction causes blood's pH to decrease - Equation 3: H2O + CO2 ←→ HCO3- + H+ After the first early lecture your new Phys Phriend ate a large breakfast and drank a very sugary drink. Consequently, you correctly realized that their morni...

A - ️️Which is a correct statement about how the three main categories of extracellular messengers could be regrouped? A. Paracrine and neurotransmitter could be combined because they travel only short distances. B. Endocrine and paracrine could be combined because fewer types of cells can release them. C. Both statements are correct about possible regroupings. D. Neither statement is correct about possible regroupings. Homeostatic Control System - ️️Set of interconnected compone...

integrating center - ️️compares conditions to set point and determines if feedback is needed (if conditions are different than set point then efferent pathway is used to make change) steady state (SS) - ️️(operating point) parameter is at set point - system isn't changing but energy is used to run HCS and maintain SS (not equal to equilibrium, which doesn't need energy to maintain the state) - energy (ATP) is limited and is needed to maintain state -- trade-offs are needed in...

Direct communication between cells in physical contact with one another is accomplished through - gap junctions The lumen of the organs of the ____ system is part of the internal environment - cardiovascular The ___ secretes the hormones ___ to regulate the body's metabolism - thyroid; T3 and T4 if the cell body of a neuron becomes more permeable to potassium, which statement below best describes the graded potential that will be generated - potassium will leave the cell, causing the m...

protein channels, endocytosis - ️️how do polar and large substance move through membrane? active transport - ️️against gradient, requires energy, based on ATP and conformation, substrate level phosphorylation - ️️bound P transferred to ADP (glycolysis, Krebs cycle, creatine) Plasma, interstitial fluid, intracellular - ️️what are the three fluid compartments? intracellular, interstitial fluid, plasma - ️️in what order from largest to smallest are the fluid compartments...
