What is an excess of end-product molecule alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?
The phenomenon you are describing is known as "feedback inhibition." In this regulatory mechanism, an excess of the end-product molecule binds to an allosteric site on the first enzyme of the metabolic pathway, causing a conformational change that reduces the enzyme's activity. This effectively shuts off the pathway, preventing the overproduction of the end product and ensuring metabolic balance within the cell. Feedback inhibition is a crucial regulatory strategy in biochemical pathways.
What else can I help you with?
Why is feedback inhibition almost always noncompetitive?
Feedback inhibition is typically noncompetitive because the end product of a metabolic pathway binds to an allosteric site on the enzyme rather than the active site. This binding alters the enzyme's conformation, reducing its activity without directly competing with the substrate for the active site. As a result, the substrate can still bind, but the overall rate of the reaction decreases, allowing for fine-tuned regulation of metabolic pathways. This mechanism ensures that the pathway's activity is modulated based on the levels of the final product, preventing overproduction.
What is a signal transduction?
A signal transduction is a really complicated process when a molecule signals to a receptor which then alters other molecules as a response to this. The signal can produce a wide variety of responses.

What feature of a limonene molecule is responsible for the colour change?
The color change in a limonene molecule is primarily attributed to its ability to undergo oxidation, which alters its molecular structure. When limonene is exposed to air or certain conditions, it can form reactive oxygen species or other derivatives, leading to this observable change in color. This transformation often involves the formation of new bonds and functional groups that can absorb light differently than the original molecule.

What does the petals on the ground that are a pathway for the dead signify in the day of the dead?
Well, I think you pretty much answered your own question there! ;) They signify a pathway for the spirits to follow to get to the alters built for them by their families! :D
What is radioactive disintegration series?
A disintegration series is the pathway of a radioactively unstable element into a stable element. The pathway alters the atomic number of the element and converts the element into another element. A common one is the uranium disintegration series.

What is the process bleaching?
An oxidizing bleach works by breaking the chemical bonds of a chromophore (part of a molecule that has color). This changes the molecule so that it either has no color or else reflects color outside the visible spectrum. A reducing bleach works by changing the double bonds of a chromophore into single bonds. This alters the optical properties of the molecule, making it colorless.

A chemical change is any change that?
In a macrscopic scale: alters colour, scent, texture.In a microscopic scale: Break bonds between atoms in a molecule and/or forms new bonds between atoms.

How does the lone pair contributes to molecular shape?
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.
How is blood intrinsically controlled?
Blood flow is intrinsically controlled by the ability of local tissues to constrict or dilate arterioles that serve them. This alters the region flow depending on the body's needs. There are three types of intrinsic control: metabolic, myogenic, and endothelial.
What change takes place in the cell membrane if a signal molecule causes a transport protein to open?
When a signal molecule activates a transport protein on the cell membrane, it undergoes a conformational change that opens a channel or alters its affinity for the molecule it transports. This allows specific substances to move across the membrane, facilitating cellular communication and maintaining homeostasis.
