Special proteins that bind to enzymes during the cell cycle are called cyclins. Cyclins regulate the activity of cyclin-dependent kinases (CDKs), which are essential for driving the cell cycle forward. The binding of cyclins to CDKs activates these kinases, allowing them to phosphorylate target proteins and facilitate key processes such as DNA replication and cell division. The levels of cyclins fluctuate throughout the cell cycle, ensuring proper timing and regulation of these critical events.

What is the stage of cell division that is responsible for cell growth and production of new organelles and enzymes?
The interphase stage of the cell cycle is responsible for cell growth and the production of new organelles and enzymes. During this stage, the cell prepares for division by replicating its DNA and synthesizing proteins necessary for cell division.
What does Krebs cycle reaction need to proceed?
The Krebs cycle (also known as the citric acid cycle) requires oxygen, acetyl-CoA (produced from the breakdown of carbohydrates, fats, and proteins), and enzymes to proceed. This cycle takes place in the mitochondria of cells and is essential for the production of energy in the form of ATP.
What cell structure is made in G1?
During the G1 phase of the cell cycle, the primary cell structures that are synthesized include organelles such as mitochondria and endoplasmic reticulum, as well as proteins necessary for DNA replication and cell growth. The cell also increases in size and prepares for the subsequent S phase, where DNA replication occurs. Additionally, key regulatory proteins and enzymes are produced to ensure proper progression through the cell cycle.
What is aerobic enzymes?
Aerobic enzymes are proteins that catalyze chemical reactions involved in aerobic metabolism, where oxygen is used to produce energy in cells. These enzymes oversee processes such as the citric acid cycle and electron transport chain, helping to break down nutrients and generate ATP for cellular functions.
What types of things do proteins do in cells?
Proteins perform a multitude of tasks in cells including acting as structural support, catalysis of chemical reactions (enzymes), molecule and ion transport, cell signaling, regulation of the cell cycle and several other important functions.
What is the role of proteolytic enzymes in the cell cycle?
Proteolytic enzymes are involved in the cell cycle by helping to degrade key proteins that regulate cell division, ensuring that the cycle progresses smoothly. They also play a role in controlling the timing and coordination of various cell cycle events, such as the degradation of cyclins that control the transition between cell cycle phases. Overall, proteolytic enzymes help to maintain the proper balance of proteins required for cell division and growth.
In what ways do enzymes control the cell cycle?
Enzymes control the cell cycle by regulating key checkpoints that determine whether the cell should proceed to the next phase. They regulate the activation and inactivation of proteins involved in cell cycle progression. Enzymes also help maintain the proper timing and coordination of events during each phase of the cell cycle.
What are cyclins and What is their functions?
What are Cyclins and what are their functions? ^^ haha I agree They are different proteins within the cell which begin to accumulate and then rapidly disappear as the cell cycle progresses. They bind to kinases (enzymes that transfer a phosphate group from ATP to other enzymes) and activate them, which activate some enzymes directly and signal the cell to synthesize other proteins needed to progress to the next phase in the cycle. Their function is to regulate the cell cycle by what I just explained.
What substances form the cyclin-cycle dependent kinase combinations that control the stages in the cell cycle?
proteins and enzyme
What monitors a cell's progress from phase to phase during the cell cycle?

What monitor a cells progress from phase to phase during the cell cycle?
a series of enzymes
What is the stage of cell division that is responsible for cell growth and production of new organelles and enzymes?
The interphase stage of the cell cycle is responsible for cell growth and the production of new organelles and enzymes. During this stage, the cell prepares for division by replicating its DNA and synthesizing proteins necessary for cell division.
Does a series of enzymes control a cell's progress from phase to phase during the cell cycle?
Yes
What monitors a cells's progress from phase to phase during the cell cycle?
A series of enzymes and cyclins
What is the general name of the proteins that internally regulate the cell cycle?
NOTHING happens within a cell that is not under the STRICT control of [proteinaceous] ENZYMES. Both structural and functional, all enzymes have ON and OFF switches that are, not too surprisingly, controlled by other proteins, which are themselves, in turn, Governed by The Cell Cycle: which begins when the Cell's cell-size-of-growth-indicators say-time-to-divide.
Whichof the following monitors a cell's progress from pashe to phase during the cell cycle?
a series of enzymes
