Internal cell regulators are proteins that respond to changes within a cell.
For example, a normal cell will not enter the mitosis stage of cell division till the entire DNA is replicated. This check is regulated by a protein within the cell. This protein is the internal cell regulator.
External regulators are proteins that respond to events outside the cell. These proteins direct cells to speed up or slow down the cell cycle, like traffic lights. For example, growth factors are one of the most important external regulators, and they stimulate the growth and division of cells. These differ from internal regulators in the fact that they respond to events inside the cell. Internal regulators allow the cell to proceed only when certain processes have happened inside the cell. Hope this helps! : )
Meiosis: Meiosis produces daughter cells that have one half the number of chromosomes as the parent cell. (Also the sexual cell cycle that requires to different cells) Mitosis: Mitosis produces two daughter cells that are identical to the parent cell. (Also the asexual cell cycle that requires only the one parent cell)
External regulators respond to events outside the cell by receiving signals from the external environment through receptors on the cell surface. These signals can activate intracellular signaling pathways that regulate gene expression, cell growth, division, or death in response to the external stimulus. This allows cells to adapt and respond to changes in their environment to maintain homeostasis.
The cell cycle is regulated by a variety of checkpoints that monitor cell growth, DNA replication, and division. Key regulatory proteins, such as cyclins and cyclin-dependent kinases (CDKs), help control progression through the cell cycle by phosphorylating target proteins. If errors or abnormalities are detected at these checkpoints, the cell cycle can be halted to allow for repair or trigger programmed cell death (apoptosis).
In the cell cycle, external regulators direct cells to either continue dividing or stop dividing based on signals from the environment. These signals help ensure that cells only divide when needed and in the proper conditions.

Internal Regulators Proteins that respond to events inside the cell are called internal regulators. Internal regulators allow the cell cycle to proceed only when certain processes have happened inside the cell. For example, several regulatory proteins make sure that a cell does not enter mitosis until all its chromosomes have been replicated. Another regulatory protein prevents a cell from entering anaphase until all its chromosomes are attached to the mitotic spindle.

internal regulators make sure the cell is ready to go on in mitosis.
Internal regulators are mechanisms within an organism that control their biological processes, such as hormones that maintain homeostasis. External regulators are environmental factors outside the organism that influence its biological responses, like temperature or availability of nutrients. Both internal and external regulators play key roles in determining an organism's growth and development.
The 3 things are cyclins, internal regulators, and external regulators. I'm not sure though thats what it says in my bio book...

Proteins called internal regulators and external regulators control the cell cycle. Internal regulatory proteins allow the cell cycle to proceed only when certain events have occurred in the cell itself. External regulatory proteins direct cells to speed up or slow down the cell cycle.
The three main regulators of the cell cycle are cyclins, cyclin-dependent kinases (CDKs), and checkpoints. Cyclins bind to CDKs to activate them at specific points in the cell cycle, triggering progression from one phase to the next. Meanwhile, checkpoints monitor cell cycle progression and can pause or stop the cycle if errors or damage are detected.

These are cyclin dependent kinases (CDKs).
