What types of molecules may not need transport proteins to be able to cross cytoplasmic membranes?
frozen [14]

The correct answer is small hydrophobic molecules.

The smaller the molecule and the more hydrophobic, or nonpolar, it is, the more rapidly it will diffuse across a membrane. It is because of the composition of membrane (lipid bilayer). By contrast, membrane is highly impermeable to charged molecules (ions), no matter how small they are.

Which element is most likely to be a nonreactive gas?
aniked [119]

Answer:

Xe

Explanation:

Cs and Na are solids in room temperature while F and Xe are gases.

The number of electrons in the outermost shell of an atom will determine its reactivity. Out of the gases given Xe and F, F ( the most electronegative element) posses 5 valence shell electrons which makes it highly reactive while Xe which is a noble gas posses 8 valence shell electrons which makes it less reactive compared to many elements.

What is energy coupling?
vagabundo [1.1K]

Answer:

c: the use of energy released from an exergonic reaction to drive an endergonic reaction.

Explanation:

<em>Energy coupling is a process involving two reactions whereby one of the reactions generate energy, and the generated energy is used to drive the other reaction. </em>

A reaction during which energy is generated is referred to as exergonic reaction while one in which energy is consumed is known as endergonic reaction. Hence, energy coupling can also be viewed as a process linking exergonic and endergonic reactions whereby the energy released in the former is used up by the latter.

A good example is illustrated by the light dependent and light independent reactions of photosynthesis during which the ATP and NADPH produced during the light dependent reaction is used to fix carbon dioxide in the light independent reaction.

<em>The correct answer is C.</em>
