1. Understanding the Question: The question asks for a specific biological or technical term that describes a solution where the concentration of water molecules and solute is equal on both sides of a cell. 2. Defining Key Terms: - Concentration: This refers to the amount of solute present ...
Thus, carbon dioxide molecules are nonpolar overall. This lack of polarity influences some of carbon dioxide’s properties. (For example, carbon dioxide becomes a gas at −77°C, almost 200° lower than the temperature at which water boils.) Figure 4.5 Physical Properties and Polarity The ...
stimulatory lipopolysaccharide (that activate Toll-like receptors) or produce curli (an amyloidogenic protein that can template α- synuclein aggregation in the gut)154,155; and depletion of bacteria producing beneficial/neuroprotective molecules such as short-chain fatty acids (deficits in which are li...
Chimeric molecules comprising at least one aptamer — a single-stranded synthetic oligonucleotide that folds into a defined architecture to specifically bind with high affinity to an RNA, a protein or another ligand — and another molecule with different biological properties. k-mer A short (3–8...
Active Transport– Active transport is the transport of molecules with the active assistance of a carrier that can transport the material against a naturalconcentration gradient. Passive Transport(Diffusion) – The movement of molecules from areas of high concentration (i.e. outside a cell) to area...
Show Answer Key Takeaways Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off. The rate of an enzyme-catalyzed reaction increases with...

Thiolase catalyzes condensation of two acetyl-CoA molecules to acetoacetyl-CoA via two steps: In the first half reaction the active site cysteine attacks acetyl-CoA to form an acetyl-S-enzyme intermediate which reacts, in the second half reaction, with the anion formerly formed from the second...
Answer Show Answer Key Takeaway Some molecules must have multiple covalent bonds between atoms to satisfy the octet rule.Exercises Each molecule contains multiple bonds. Draw the Lewis diagram for each. The first element is the central atom. CS2 C2F4 COCl2 Each molecule contains double bonds. ...
Because elemental chlorine is a diatomic molecule, we need four chlorine molecules to get a total of eight chlorine atoms. We add another 4 in front of the Cl2 reactant:CH4 + 4Cl2→ CCl4 + 4HClNow we check: each side has one carbon atom, four hydrogen atoms, and eight chlorine atoms...
