diffusion` correct answers distribution of ion in water over time until equilibrium is reached polar molecule correct answers uneven charge distribution hydrophilic correct answers water-loving, charged interaction of charge with dipole moments hydrophobic correct answers water fearing (i.e. lipids, triglycerides) uncharged triglycerides correct answers glycerol and 3 molecules of fatty acid glycerol correct answers 3 carbon alcohol trans-fat correct answers when the carbon...

How is a tertiary structure held together? - correct answer the hydrophobic effect, Hydrogen bonds, and ion-ion interactions What would be the consequence of changing an amino acid that helps to hold together tertiary structure? - correct answer Changing the amino acid would change the structure therefore making it non-functional. How is a quarternary structure held together? - correct answer By the hydrophobic effect, hydrogen bonding, ion-ion interactions and Van der Waals interact...

what are membrane functions? correct answers 1) separate cells from the external medium to create an intracellular environment of unique and defined composition 2) allow selective transport of substrates in and out of the cell 3) provide a location for specialized pathways and processes (energy conversion of mitochondria) 4) rapid changes in electric potential across the membranes of neurons as basis of the nervous system 5) localization of receptors to facilitate response to physiological s...

What vitamin does not travel through the bloodstream in the form of a lipid micelle? - Vitamin C Which lipid has a 4-ring structure? - Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? - fasting A patient who is on a no-fat diet is at particular risk of deficiency in: - Vitamin A During starvation, triglycerides can help supply some of the body's glucose needs. Which breakdown product of triglycerides can be used to make glucose? - glycerol CH...

Electric Dipole Moment correct answers Neutral molecule with uneven charge distributions (partial charges) e.g. H2O Diffusion correct answers Movement of molecules from areas of high to low concentrations e.g. Volatile Perfume distributing through the air Osmosis correct answers Diffusion of WATER through a membrane e.g. Aquaporins (biological proteins) Hydrophilicity correct answers "Water Loving" e.g. Charged ions that interact with the Electric Dipole Moment in water. (Soluble) ...

Dipole Moment correct answers The difference in charge between atoms in a water molecule Water Molecules Interact With Each Other Through _______ correct answers Hydrogen Bonds Why is water liquid at room temperature? correct answers Because the hydrogen bonds within it are constantly breaking and reforming on different molecules (moving around) Shell of Hydration correct answers The oxygen atoms in water will orient themselves towards positively charged ions in water, the hydrogen atom...

A bond in which electrons are shared between atoms is a _______ bond. correct answers covalent Water molecules are attracted to each other and form ________ bonds. correct answers hydrogen Sodium (Na+) will be attracted to what portion of a water molecule. correct answers oxygen _______ is the diffusion of water molecules through a semipermeable membrane from a place of higher water concentration to a place of lower water concentration until the concentration on both sides is equal. cor...

Homeostasis correct answersRegulation of the body's internal environment; must respond to environmental challenges. Law of Mass Balance correct answersLaw that states that the amount of substance in the body is to remain constant, any gain must be offset by an equal loss. Negative feedback loop correct answersSomething is wrong in a body system that is sensed and there is a response that is generated which returns the system to a homeostatic state (stabilizes variable). Positive feedba...
