Growth factors allow the cells to rapidly divide once they are anchored to a surface. Once the cells use up all of the growth factor (or they start to bump into each other) they will stop diving. Kinase is a regulatory protein that aids in the "stop" and "go" portion of 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.


What are the factors that control the cell growth and division?

the factors that influence cell division is the leading contrary that helps the cell division. one factor is the growth of the cell that is being divided. another factor is the size and shape of the cell. a cell can be a nerve cell or a muscle cell which rarely divides.


Cell cycle is regulated by?

The timings of the cell cycle are controlled by cyclins (protein complexes) and cyclin-dependent kinases / CDKs (enzymes).The cyclins activate the CDKs, which affect the cell cycle at three important checkpoints:Late in the G1 stage of the cell cycle, triggering the cell to move into the S phase.Late in the G2 stage of the cell cycle, triggering the cell to move into mitosis.The M (metaphase) checkpoint, triggering entry into anaphase.


Which does not control the cell cycle?

The endoplasmic reticulum does not control the cell cycle. The cell cycle is primarily regulated by proteins such as cyclins and cyclin-dependent kinases, along with checkpoints and signaling pathways that monitor DNA integrity and cell growth. The endoplasmic reticulum's main functions include protein synthesis, lipid metabolism, and calcium storage.


Increases in the enzymatic activity of some protein kinases important for the regulation of the cell cycle are due to?

phosphorylation by other kinases, which can switch them from an inactive to an active state. This post-translational modification can be triggered in response to specific signals, allowing for precise control of cell cycle progression.

Kinases and cyclins are internal factors that?

regulate the cell cycle by controlling various checkpoints. Kinases phosphorylate proteins to initiate specific cell cycle phases, while cyclins bind to kinases to activate them at different stages of the cycle. Both play critical roles in ensuring proper cell division and maintaining genomic integrity.


How do growth factors influence the progression of the cell cycle?

Growth factors are signaling molecules that can stimulate cells to grow and divide. They play a crucial role in regulating the progression of the cell cycle by activating specific proteins called cyclin-dependent kinases (CDKs). These CDKs help control the timing and progression of different phases of the cell cycle, such as G1, S, G2, and M phases. By activating CDKs, growth factors can promote cell proliferation and regulate cell cycle progression.


Kinases and cyclins are internl factors that?

Kinases and cyclins are internal factors that play crucial roles in regulating the cell cycle. Kinases are enzymes that add phosphate groups to specific substrates, often activating or deactivating proteins involved in cell cycle progression. Cyclins are regulatory proteins whose levels fluctuate throughout the cell cycle, activating cyclin-dependent kinases (CDKs) to drive the transition between different phases. Together, they ensure proper timing and coordination of cell division and growth.


What is the category of enzymes that control the cell cycle called?

Cyclin-dependent kinases.


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

cyclin dependent kinases,CDK's


What are the 5 control factors for mitosis?

The five control factors for mitosis are cyclin-dependent kinases (CDKs), cyclins, checkpoints, growth factors, and tumor suppressor genes. These factors help regulate the progression of the cell cycle and ensure that mitosis occurs correctly.


What statements regarding the cell cycle control system is false?

A false statement regarding the cell cycle control system could be that it is completely independent of external signals. In reality, the cell cycle control system is heavily influenced by external signals, such as growth factors and DNA damage, that regulate the progression through different phases of the cell cycle.

What is the protein that regulates cell cycle?

The protein that regulates the cell cycle is called cyclin-dependent kinase (CDK). CDK is activated by binding to specific proteins called cyclins at different stages of the cell cycle. Together, CDK and cyclin complexes regulate the progression of the cell cycle by phosphorylating target proteins that control cell division.
