What else can I help you with?
What is used to help break down the nuclear membrane?
Enzymes called kinases and phosphatases are used to help break down the nuclear membrane during cell division. These enzymes modify proteins that make up the nuclear membrane, causing it to disassemble.
What is the difference between integral and peripheral membrane proteins in terms of their location and function within the cell membrane?
Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are attached to the surface of the membrane. Integral proteins are involved in transporting molecules across the membrane and cell signaling, while peripheral proteins often serve as enzymes or play a role in cell structure and shape.
What are the key differences between integral membrane proteins and peripheral membrane proteins in terms of their structure and function within the cell membrane?
Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are only temporarily associated with the membrane. Integral membrane proteins have hydrophobic regions that interact with the lipid bilayer, while peripheral membrane proteins do not penetrate the lipid bilayer. In terms of function, integral membrane proteins are involved in transport, signaling, and cell adhesion, while peripheral membrane proteins often serve as enzymes or participate in cell signaling pathways.
What are the types of proteins synthesize in the free ribosome?
Free ribosomes synthesize proteins that are soluble in the cytoplasm, such as enzymes, structural proteins, and proteins involved in intracellular signaling pathways. These proteins do not have a specific subcellular localization and function within the cytoplasm of the cell.
Which part of the cell membrane helps chemical reactions happen?
The proteins embedded in the cell membrane, such as enzymes and receptors, facilitate chemical reactions by serving as catalysts or by binding to specific molecules to initiate signaling cascades. These proteins play a crucial role in regulating the transport of substances in and out of the cell and in transmitting signals across the membrane.
What proteins in the cell membrane help import biochemical reactions inside the cell?
The proteins you speak of are enzymes. Without enzymes present majority of biochemical reactions would not be able to take place. *Enzymes are a polymer of proteins.
What are enzymes inside of cells called?
Enzymes are proteins, which are comprised of chains of amino acids. All enzymes are proteins (but not all proteins are enzymes)
What type of macro-molecule make up transporters carriers and enzymes in the plasma membrane?
Transporters, carriers, and enzymes in the plasma membrane are primarily made up of proteins. These proteins can span the membrane, facilitating the movement of substances in and out of the cell, or they can act as enzymes that catalyze biochemical reactions. The specific structure and function of these proteins are determined by their amino acid sequences, which are encoded by the cell's DNA. Additionally, these proteins may interact with lipids and carbohydrates, contributing to their overall functionality in the membrane.

What part of the membrane helps chemical reactions happen?
Proteins in the membrane, such as enzymes, play a crucial role in facilitating chemical reactions by providing a suitable environment for the reaction to occur. These proteins can catalyze specific reactions and help transport molecules across the membrane to enable cellular processes.
Cell membrane proteins do not include?
Proteins not found in the cell membrane include histones (associated with DNA in the nucleus), cytoskeletal proteins (maintain cell shape and structure), and enzymes located in the cytoplasm or organelles.
What protein classes are not found as membrane proteins - identity markers or receptors or transport channels or enzymes or hormones?
Enzymes and hormones are protein classes that are not typically found as membrane proteins acting as identity markers, receptors, or transport channels. Enzymes catalyze chemical reactions inside cells, while hormones are signaling molecules released into the bloodstream to regulate various physiological processes.
What is the difference between integral and peripheral membrane proteins in terms of their location and function within the cell membrane?
Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are attached to the surface of the membrane. Integral proteins are involved in transporting molecules across the membrane and cell signaling, while peripheral proteins often serve as enzymes or play a role in cell structure and shape.
Why do you say that all enzymes are not proteins?
Enzymes are proteins which act as catalysts for various reactions that occur in cells. (A catalyst speeds up a reaction without being permanently altered itself). Some proteins function in other ways like transporting substances across the cell membrane or providing structure. Therefore, all enzymes are proteins but not all proteins are enzymes. Uhm Ribozymes are enzymes that are not protein
What proteins are embedded in the plasma membrane?
They are called integral proteins

Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are only temporarily associated with the membrane. Integral membrane proteins have hydrophobic regions that interact with the lipid bilayer, while peripheral membrane proteins do not penetrate the lipid bilayer. In terms of function, integral membrane proteins are involved in transport, signaling, and cell adhesion, while peripheral membrane proteins often serve as enzymes or participate in cell signaling pathways.
What macromolecules makes up transporters carrier and enzymes in the plasma membrane?
Transporters, carriers, and enzymes in the plasma membrane are primarily made up of proteins, which are macromolecules composed of amino acids. These proteins can span the membrane, facilitating the movement of ions and molecules across it, or act as enzymes to catalyze biochemical reactions. Additionally, some of these proteins may be glycosylated, meaning they have carbohydrate groups attached, which can play a role in cell recognition and signaling. Lipids, particularly phospholipids, also contribute to the structural integrity of the plasma membrane but are not directly involved in the functions of transporters and enzymes.
