False. Feedback inhibition occurs when an enzyme acting early in a pathway is inhibited by the accumulation of a product late in the pathway
What is inhibition ?Inhibition is the conscious or unconscious restriction or restraint of a process or behavior, especially of urges or wants. The ability to inhibit oneself from acting on some impulses, such as the desire to hit someone in a fit of rage, and to delay the satisfaction of pleasurable activities allows one to perform vital social functions. When two desires are perceived that are in conflict, conscious suppression often occurs in daily life (e.g., the desire to eat a rich dessert versus the desire to lose weight).
According to psychoanalytic theory, inhibition serves as a mediator between the id and the superego, or conscience, and is largely unconscious (primitive desires). The socially imposed inhibitions known as taboos, such as those prohibiting incest or murder, are elevated to the level of moral prohibition.

Transmission of nerve impulses relies on the concentrations of ______ in the neuron.
Transmission of nerve impulses relies on the concentrations of sodium and potassium in the neuron.
Why is conduction at synapses one way?Conduction at synapses is always one way because, at each synapse, only one neuron has neurotransmitter (which is released into the synaptic cleft), while the other has the neurotransmitter receptors that open Na+ ion channels. Therefore, the transmission can never be in the opposite direction.
The sodium potassium pump maintains an electrical gradient across the plasma membrane of a neuron when it is not actively transmitting a nerve impulse.

Why would scientists find it useful to know the densities and volumes of different materials? Please respond in 1–2 complete sentences using your best grammar.
It is useful to know the densities and volumes of different materials as it helps in deducing various properties pf the material and also helps to perform certain calculation.
Density is defined as the mass of any substance divided by its per unit volume. Density is actually the measure of the degree of the compactness of any material. Usually, heavier substances are more dense the lighter ones.
Volume can be defined as the three-dimensional space any object can occupy in the space. The volume is measured in cubic units. The formula for calculating volume may differ from one object to another, depending upon its shape.

Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. Which level of protein structure most directly leads to this binding specificity?.
Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. The tertiary structure of protein leads to this binding specificity.
The tertiary structure of proteins helps in building complex three-dimensional structures proteins. This three-dimensional structure allows proteins to represent their functional groups on the outer side which can then easily interact with other molecules such as glucose.
The specificity of the proteins is maintained by the three-dimensional structure that it gets as a result of the tertiary structure.
The specific three-dimensional structure of enzymes where specific molecules can fit is referred to as the active site of the enzyme. Due to this specificity, only the right molecules can fit into the active site.

Genes, and they are found in the nucleus.
What is Genes?The term "gene" can refer to a variety of biological concepts. Mendelian genes are the fundamental building blocks of heredity, and molecular genes are DNA sequences that are translated to create functional RNA. Noncoding and protein-coding genes are the two different categories of molecular genes.
The DNA is initially transcribed into RNA when a gene is expressed. A protein that fulfills a function can be directly generated from the RNA or it can serve as the intermediary template. Phenotypic qualities are passed down through gene inheritance from an organism to its progeny. Numerous DNA sequences known as genotypes are composed of these genes.

The egg will hatch when it reaches a temperature of 36°C. Zone of Hatching Potential is the official name of this region. It ranges from 35 to 40.5°C.
What exactly is a zone of potential for a hatch is "Temperatures between 35 and 40.5°C (84.5 and 104.9°F) are permissible for egg emergence"
The ideal temperature (for hens) is 37.5 degrees Celsius (99.5 degrees Fahrenheit); above this temperature, the hatch rate will be reduced and there will be a greater proportion of deformed and crippled chicks.
Any temperature increase above 40.5°C (104.9°F) will result in the death of all embryos.
Growth will be hindered and mortality will rise at constant temperatures in this range, although below the optimal.

Model 1 undergoing diffusion? Explain.
Yes, According to this definition, the cell in Model 1 is undergoing diffusion from a higher concentration inside the cell to an area of low concentration outside the cell.
What happens when the cell undergoes diffusion?Water is diffusing through the cell from a greater concentration to a lower concentration. This would keep on until the water concentration on both sides of the membrane was equal (dynamic equilibrium is established).Due to their size, the sugar molecules are not diffusing. Through channel proteins, which run on ATP for energy, sugar molecules can enter cells.A special kind of diffusion takes place here which is known as osmosis.Osmosis is defined as the passage of water molecules through a semipermeable membrane from an area with a greater water concentration to one with a lower concentration of solution (i.e., lower concentration of water).To learn more about Osmosis visit:

Translation of mRNA- There are two main components to it: a big and a small subunit. The transfer RNAs, or tRNAs, that are floating in the cell are brought together with the mRNA to be translated by the ribosome. mRNA and the polypeptide chain that the cell must assemble are coordinated by adaptor molecules called tRNAs.
Translation of amino acid- As ribosomes move along an mRNA strand during translation, they assemble the sequence of amino acids specified by the mRNA to create a protein with the aid of proteins known as initiation factors, elongation factors, and release factors.
UAC serves as the anticodon for AUG. This tRNA is bringing in a methionine at its other end and has the anticodon UAC. No water molecule is produced as UAC is the first amino acid.

Homeowners have the option of building porches, decks, and fencing with composite boards or traditional wood boards. Traditional wood decking is made from pressure-treated lumber that resists rot, mold, and insects. The process of pressure treating wood also involves soaking the boards in a protective chemical solution. The wood boards still have to be sealed against moisture on a routine basis. Composite boards are made by pressing together ground wood scraps and recycled plastic, which is heated and pressure-treated and then coated with UV and stain-resistant coatings. Composite boards do not need to be sealed against moisture.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. In what location of the cell would you begin this observation?.
You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. Endoplasmic reticulum (ER) is the place where this observation will begin.
As all enzymes are proteins hence we will begin with the endoplasmic reticulum to study the whole process from the formation of enzymes. The endoplasmic reticulum is the site that plays a central role in the synthesis of a protein.
Ribosomes, the sites where proteins are formed after the translation of mRNA, are present on the membranes of the rough endoplasmic reticulum (RER). After the synthesis of a protein, the rough endoplasmic reticulum (RER) also transports the proteins to the Golgi apparatus where the protein is packaged and processed.
