What else can I help you with?
A specific protein that recognizes certain molecules bringing them across the membrane?
The protein you are referring to is likely a transporter protein, which is responsible for facilitating the transport of specific molecules across the cell membrane. These transporter proteins bind to their target molecules on one side of the membrane and undergo a conformational change to transport the molecules to the other side. Examples include glucose transporters and ion channels.
Proteins that attach molecules in order to deliver them to another site?
These proteins are likely transport proteins, such as carrier proteins or channel proteins, which bind to specific molecules and facilitate their movement across cell membranes or through the bloodstream. These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
A steroid hormone acts on a target cell by?
binding to a specific receptor located inside the cell. This hormone-receptor complex then enters the nucleus and binds to specific DNA sequences, regulating the expression of target genes. This can lead to changes in protein synthesis and cellular function in the target cell.
How do carriers proteins recognize substances to transport an active transport?
Carrier proteins recognize substances for active transport through specific binding sites that have a complementary shape and chemical properties to the target molecule. These binding sites often involve interactions such as hydrogen bonds, ionic bonds, and hydrophobic interactions, allowing for selective recognition. Once the target substance binds to the carrier protein, it undergoes a conformational change that facilitates the transport of the substance across the membrane, often against its concentration gradient, using energy from ATP or other sources. This specificity ensures that only the intended molecules are transported, maintaining cellular homeostasis.
What is the name of enzymes that control the activities of other proteins by phosphorylating them?
The enzymes that control the activities of other proteins by phosphorylating them are called protein kinases. They transfer phosphate groups from ATP to specific amino acids on target proteins, thereby regulating their functions. This phosphorylation process plays a crucial role in signal transduction pathways within cells.

How do hormone and target cell recognize one another?
Hormones are specific molecules released by endocrine glands into the bloodstream. Each hormone binds to a specific receptor protein on the surface of the target cell. The receptor protein acts like a lock and key, ensuring that only the specific hormone can bind and trigger a cellular response in the target cell.

What protein changes shape when ca2 plus binds to it?
Calmodulin is a protein that changes shape when it binds to calcium ions. This change in shape allows calmodulin to interact with and activate various target proteins involved in signaling pathways within cells.
What is a mimetic drug?
—Mimetics usually small molecules that resemble (or mimic) a domain of an endogenous compound or target —3 general criteria for mimicry —Structural —Binding —Functional There three types of mimetics available: o Modified proteins (similar to endogenous protein with minor changes) o Peptidomimetics ( molecules that no longer contain any peptide bonds but has the pharmacological activity of peptides) o Non-protein mimetics (non-protein small molecules that mimic endogenous secondary structure and binding characteristic) Protein mimetics that are better tolerated, more effective and lower cost may be produced.
What type of vitamin requires a protein carrier to traverse the blood stream?
Fat-soluble vitamins (such as vitamins A, D, E, and K) require a protein carrier to traverse the bloodstream since they are not water-soluble and cannot travel freely in the blood. These vitamins bind to specific carrier proteins to be transported in the bloodstream and reach target tissues in the body.
What Equipment is used in the sport of shooting?
Firearm, ammunition, target, target carrier, spotting scope.
What happens if the shape of a protein is altered and how does it impact its function?
When the shape of a protein is altered, it can affect its ability to function properly. Proteins rely on their specific shape to interact with other molecules and carry out their biological roles. If the shape is changed, the protein may not be able to bind to its target molecules or perform its intended function, leading to potential disruptions in cellular processes and overall health.
What is percent recovery in protein purification?
When you use methods such as Solvent precipitation, you precipitate a protein molecule but this protein molecule normally does not have the same structure as that of protein in a solution (for example disulfide bonds do not connect the same amino acids) and it is not easy to change this to that of original structure even when the same solution is present. The percent of recovery means the percent that these denatured protein molecules can gain the same structure that they have in the solution before precipitation.
How does the antibody protein A function in the immune system to target and neutralize pathogens?
Antibody protein A works by binding to specific molecules on the surface of pathogens, marking them for destruction by immune cells. This helps to neutralize the pathogens and prevent them from causing harm in the body.
Where can one purchase an infant carrier?
One can purchase an infant carrier by going to Target. Target sells a variety of infant carriers both in its retail stores as well as from its online store on its website.
Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
