How do cats drink? Scientists using high-speed video have that cats use an interesting technique to drink aqueous substances like water and milk. Four times a second, the cat touches the tip of its tongue to the water and draws a column of water up into its mouth (as you can see in the photo), which then shuts before gravity can pull the water back down. Describe how the properties of water allow cats to drink in this fashion, including how water’s molecular structure contributes to the process.

- Manufacturers make carbonated drinks by forcing pressurized carbon dioxide gas into flavored water. A chemical reaction between water molecules and some of the CO2 molecules creates hydrogen ions (H+) and bicarbonate, which is a buffer. In your opinion, is this reaction likely to raise the pH of a soda above 7, or lower it? Give your reasoning.arrow_forwardDiscuss Concepts You place a metal pan full of water on the stove and turn on the heat. After a few minutes, the handle is too hot to touch but the water is only warm. How do you explain this observation?arrow_forwardIn crime novels, a dead body is often referred to as a “stiff” because the limbs don’t move until after decomposition sets in. Trace a pathway that would begin with the stiff not breathing and conclude with stiff muscles. Make sure to describe the key molecules in detail and how they contribute to stiffness.arrow_forward
- Many compounds taste sweet to humans. Sweet taste results when a molecule binds to the sweet receptor, one type of taste receptor, on the surface of certain tongue cells. The stronger the binding, the lower the concentration required to saturate the receptor and the sweeter a givenconcentration of that substance tastes. The standard free-energy change, ΔG°, of the binding reaction between a sweet molecule and a sweet receptor can be measured in kilojoules or kilocalories per mole.Sweet taste can be quantified in units of “molar relative sweetness” (MRS), a measure that compares the sweetness of a substance to the sweetness of sucrose. For example, saccharin has an MRS of 161; this means that saccharin is 161 times sweeter than sucrose. In practical terms, this is measured by asking human subjects to compare the sweetness ofsolutions containing different concentrations of each compound. Sucrose and saccharin taste equally sweet when sucrose is at a concentration 161 times higher than…arrow_forward"If you add carbon dioxide to seawater, as occurs when bacteria or animals respire or atmospheric CO2 dissolves into seawater, which of the following will happen?" Some of the H+ ions in seawater will combine with CO2 to make HCO2 The carbon dioxide will combine with oxygen and reduce the oxygen concentration. "The H+ derived from CO2 will combine with carbonate, CO32-, to form bicarbonate" pH will go up. "Nothing will happen, since the ocean water is well buffered via its alkalinity.

- In the stomach, parietal cells are responsible for the formation of the gastric juice. During acid secretion, the pH in the stomach is estimated to be pH = 2, whereas parietal cells maintain an intracellular pH =7.35. The transmembrane potential of parietal cells is typically -70 mV. Body temperature 37°C. 1) Calculate the proton gradient concentration across the parietal membrane 2) Calculate the free energy change associated with the secretion of 1 mole of H* 3) Do you think that Ht transport can be driven by ATP hydrolysis at the ratio of one molecule of ATP per H* transported? You can use your textbook or other sources to check AG for ATP hydrolysis 4) If H* where free to move back to into the cell, calculate the membrane potential that would be required to prevent them to do soarrow_forwardHome Activity: Gastric juice is a juice secreted by the stomach. It contains an enzyme called pepsin. To show the importance of pepsin in the digestion of protein.

- You are studying the effects of temperature and lipid composition on membrane fluidity using artificial membranes containing only one or a few kinds of lipids and no proteins. Assume that you and your lab partner have made the following artificial membranes: Membrane 1: Made entirely of phosphatidylethanolamine. Each of the two chains of the fatty acids is 18 carbon in length and both are completely saturated. Membrane 2: Made entirely of phosphatidylethanolamine with 14-carbon fatty acid chains. only one fatty acid tail contains a double bond, the other one is completely saturated. Membrane 3: Made entirely of phosphatidylethanolamine with 14-carbon fatty acid chains. Both fatty acid tails have a single double bond. Predict the transition temperature of the above-mentioned membranes.arrow_forwardPart A: Explain solubility of vitamins Food additive E307 (alpha-tocopherol, vit. E), and ascorbic acid (vit. C) are essential nutrients in human diet due to their antioxidant properties. They have very different solubilities. In contrast to vit. A, vit. E is insoluble in water. It is recommended that foods rich in vitamin E be taken with fatty ingredients (think salad dressing etc). • Draw the structures of both vitamins and explain their different solubilities in water. • Draw the picture illustrating solvation of vit. C in water and describe intermolecular interactions that facilitate this process. What type of intermolecular interactions help vitamin E be soluble in oils (fatty acids such as linoleic acid)? Part B: Explain observed boiling point The two molecules shown in Fig. 1 are constitutional isomers but have drastically different boiling point. Using a drawing and no more than 5 sentences explain how why compound B (butyramide) has higher boiling point. A O во NH2 153 °C 216…arrow_forwardDrugs are small molecules that often occur in either a neutral or a charged form, depending on pH. For example, aspirin can be either neutral or lose a proton to be negatively charged. When aspirin is charged, it does not diffuse well into the body. pH varies in the gastrointestinal track. Since the stomach has a low pH (pH=3), it has a larger concentration of neutral aspirin (10-3 M), while the small intestine (pH=6) has a smaller neutral aspirin concentration (10-6 M). For the following, assume that the neutrally charged aspirin molecule has a diffusion coefficient through the cell of 1 x 10-6 cm2/s.arrow_forward
