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.
DIFFERENCES:
Internal regulators only respond only to the inside, while external regulators respond only to the outside.
SIMILARITIES:
Both internal and external regulators can stop their processes.
Internal regulators respond to events occurring inside of a cell, and external regulators respond to outside events.
An internal regulator regulates the inside of a cell while an external regulator only regulates the outside of a cell.
well if you have ever seen a cow you would know they come in different colors, so just like cells they can come in different colors
Internal goes in external goes out
The cyclin-kinase system.
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! : )
By injecting a protein found from a cell in mitosis into a non-dividing cell, a mitotic spindle forms. The protein was later called cyclin. Cyclins regulate the timing of the cell cycle.
External regulators direct cells to speed up or slow down the cell cycle.
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)
speed up or slow down the Cell Cycle
it does stuffage
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 are proteins that respond to activity within a cell.
internal regulators make sure the cell is ready to go on in mitosis.
This indicates that the cell is not responding to the internal regulators inside the cell.
The 3 things are cyclins, internal regulators, and external regulators. I'm not sure though thats what it says in my bio book...

mitoconderia
to tell the cell when to perform certain fucntions such as cell division and DNA replication

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.
Cyclins and regulatory proteins. Regulatory proteins include internal regulators and external regulators
External regulators direct cells to speed up or slow down the cell cycle.
