What marks and sorts molecules to be sent to different destinations?

Proteins called sorting signals on molecules determine where they will be sent within the cell. These signals are recognized by specific receptors and transport proteins that guide the molecules to their correct destination, such as different organelles or out of the cell. This process helps maintain cellular organization and function.


What is the process by which large molecules enter a cell through pouches in the membrane?

The process by which large molecules enter a cell through pouches in the membrane is called endocytosis. During endocytosis, the cell membrane forms a pouch around the molecule, encloses it, and brings it into the cell as a vesicle. This allows the cell to take in larger molecules that would not be able to pass through the membrane on their own.


How are the smaller molecules o2 and co2 able to pass through the openings of the cell membrane?

passive transport by diffusion


What type of molecules that give instructions during cell division?

The molecules that give instructions during cell division are primarily proteins called cyclins and cyclin-dependent kinases (CDKs). These molecules regulate the progression of the cell cycle by activating specific processes at different stages of cell division. Cyclins and CDKs form complexes that drive the cell through each phase of the cell cycle.


Describe the conditions needed for molecules to enter a cell passively?

Molecules can enter a cell passively through processes like simple diffusion or facilitated diffusion. For this to occur, the molecule must be small, nonpolar, and/or able to pass through ion channels or carrier proteins. Additionally, there must be a concentration gradient across the cell membrane to drive the movement of molecules into the cell.

What moves substances in and out of a cell?

Substances are moved in and out of a cell through various processes such as diffusion, facilitated diffusion, active transport, and endo/exocytosis. These processes involve either the movement of molecules down their concentration gradient or the use of energy to transport molecules against their concentration gradient.


Diffusion osmosis active transport all of these are methods by which a cell?

Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.


Does molecules have cell?

No, molecules do not have cell, rather a cell have molecules in it.

Why are pores in the cell membrane different sizes?

They selectively allow certain size molecules to enter, or not to enter, the cell.


What is the family of molecules that control the cell cycle called?

The family of molecules that control the cell cycle is called cyclins and cyclin-dependent kinases (CDKs). These molecules regulate cell cycle progression by activating or inhibiting key processes at different checkpoints throughout the cell cycle.


The cell is dependent on outside sources of organic molecules that can be used to produce energy because?

the cell needs these organic molecules as a source of carbon and energy to fuel its metabolic processes. Without these molecules, the cell would not be able to perform essential functions like growth, maintenance, and reproduction. Organic molecules also provide the building blocks for various macromolecules required by the cell.

How oxygen enters the cells?

Oxygen is able to go into a cell by diffusion. The oxygen molecules are small enough to go through the cell membrane with that process.

A chromosome contains many genes that are transcribed into different what?

A chromosome contains many genes that are transcribed into different RNA molecules. These RNA molecules can serve as templates for protein synthesis or have other functions in the cell.
