How do external regulators respond to events outside the 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.
What are external regulators?
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! : )
What are the two types of regulators in 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)
How is the cell cycle regulated?
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).
What is the Cell cycle Gap O phase?
The Gap 0 phase (G0) is a resting phase in the cell cycle where cells are not actively dividing. Cells in G0 are in a quiescent state and can re-enter the cell cycle when stimulated. This phase is important for maintaining cellular homeostasis and responding to external signals.

What are specialized proteins that both regulate the cell cycle and cause it to occur?
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.
What arte the 3 things that regulate the cell cycle?
The 3 things are cyclins, internal regulators, and external regulators. I'm not sure though thats what it says in my bio book...

What is the internal regulatory proteins effect?
mitoconderia
What are the 3 things that regulate 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.
What directs cell growth and reproduction?
Cell growth and reproduction are directed by the cell cycle, a series of events that lead to cell division. Key regulators of the cell cycle include checkpoints that monitor DNA integrity, external signals from the environment, and cyclin-dependent kinases that control progression through different phases of the cell cycle. These regulators ensure that cells only divide when conditions are favorable and that DNA is accurately replicated and distributed to daughter cells.
What are two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
What two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
What controls the rate at which cells divide?
The rate at which cells divide is controlled by various factors, including signals from the environment, the presence of growth factors, and internal regulators such as cyclin-dependent kinases. These factors coordinate and regulate the cell cycle to ensure proper cell division.
