The reaction that increases with catabolism is A, ΔG known as the free energy change.

Catabolism is a type of metabolic pathway that breaks down complex molecules into simpler molecules. This process releases energy, which can be used by the cell to perform other functions. The ΔG of a reaction is a measure of the free energy change that occurs during the reaction.

A negative ΔG indicates that the reaction is spontaneous and will occur without any input of energy. A positive ΔG indicates that the reaction is non-spontaneous and will not occur without an input of energy.

Competitive inhibition of a kinase by a drug molecule will increase the Km value and have no effect on the Vmax value, while non-competitive inhibition will decrease the Vmax value and have no effect on the Km value.

Assuming that the kinetics of a phosphorylation reaction carried out by a kinase can be appropriately described by the Michaelis-Menten relationship, competitive inhibition of this kinase by a drug molecule will lead to an increase in the Michaelis-Menten constant (Km) and no change in the maximum reaction rate (Vmax).
Competitive inhibition occurs when a drug molecule binds to the active site of the enzyme, preventing the substrate from binding and therefore inhibiting the reaction. This leads to an increase in the Km value, as more substrate is required to achieve the same reaction rate. However, the Vmax remains unchanged, as the maximum reaction rate can still be achieved if enough substrate is present to outcompete the inhibitor.
In contrast, non-competitive inhibition occurs when a drug molecule binds to a site other than the active site, causing a conformational change in the enzyme and reducing its activity. This leads to a decrease in the Vmax value, as the maximum reaction rate is reduced, but no change in the Km value.

Answer:

Because roots get more water then the stem does, it absorbs at least 60% of the water, and if you use a nail that goes into water, it rusts, so that means that it's darker than others.

Explanation:

If you take a nail and place it under water, that means its getting 100% of the water, so it's the same thing with plants. Another reason that this is happening is that its a sign that a plant is unhealthy. So make sure to give it a lot of water( but not too much or it will drown) so it stays a healthy and happy plant.

The formation of ionic compounds is due to when opposite charges attract and like charges repel, the attraction of opposite charges makes ionic bonds in the compounds.

It is the kind of bonding in which electrostatic attraction happens, through which ionic compounds are formed.

Ionic bonds set the chemical connection in which one atom loses valence electrons and which are gained by another atom, the atoms involved in this connection form the more stable noble gas electrical state.

This bonding is different from covalent bonding, in covalent bonding there is sharing of the pairs of electrons making it more strong than ionic.

Therefore, ionic compounds form because opposite charges attract each other, leading to ionic bonding.

Answer:

There is no cartilage but there is epithelium

Explanation:

The pharynx of the human respiratory system does not contain cartilage.

The pharynx,  part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for  air and food. The gorge is made up of several regions, each with its own distinctive features.

The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated  epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.

These regions also lack cartilage but  are lined with  stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

Transport processes that do not require energy include simple diffusion, osmosis, and facilitated diffusion.

Simple diffusion is a type of passive transport that, as the name implies, is simply the movement of a solute when the electrochemical potentials on opposite sides of a permeable barrier differ.Simple diffusion, like all other passive transport mechanisms, involves the movement of molecules along a concentration gradient until the concentration of solute on either side is uniform. Osmosis is the movement of a solvent (such as water) through a semipermeable membrane (such as that of a living cell) into a solution with a higher solute concentration, which tends to equalize the solute concentrations on both sides of the membrane. a process of absorption or diffusion suggestive of the flow of osmotic action (see DIFFUSION sense 3a). Facilitated diffusion is a type of facilitated transport that involves the passive movement of molecules along a concentration gradient that is guided by the presence of another molecule, typically an integral membrane protein that forms a pore or channel.

Answer:

a system of naming plants and animals in which each species is given a name consisting of two terms of which the first names the genus and the second the species itself.

Explanation:

hope this helps ^w^

Answer:

In biology, there is a system for naming species called binomial nomenclature. It consists of two Latin names, the first of which designates the genus and the second of which designates the species that belongs to that genus. The first letter of a species name is not capitalised, whereas the first letter of a genus name is always capitalised. Italics are always used to denote the species name.

Explanation:

Carl Linnaeus, a Swedish naturalist, developed the binomial nomenclature, which is still in use today. This methodology offers a consistent method for naming species and enables straightforward communication among scientists as well as across national boundaries and linguistic barriers.

For example, the domestic cat's scientific name is Felis catus. Felis, the first term, refers to the genus, and catus, the second name, to the species found in that genus.

How is the shape and size of red blood cells related to their function?

This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.

Explanation:

The spontaneity of a reaction is determined by the change in Gibbs free energy (∆G) of the reaction. If ∆G is negative, the reaction is spontaneous (i.e., it can occur without an external input of energy), whereas if ∆G is positive, the reaction is non-spontaneous (i.e., it requires an external input of energy to occur).

From the given reactions:

We see that reactions 1 and 2 both have negative ∆G values, indicating that they are spontaneous reactions. However, reaction 3 has a positive ∆G value, indicating that it is a non-spontaneous reaction.

Therefore, reaction 3 (Glutamic acid + NH3 → Glutamine) is the non-spontaneous reaction among the given reactions.
