Front

What is the result of mitosis?

Back

Mitosis results in 2 identical diploid cells.

Front

Which of the following is NOT involved in the transduction step?

Back

Ligands are NOT involved in the transduction step.

Front

What is the role of cyclin in relation to CdK?

Back

Cyclin interacts with CdK to initiate the mitotic phase.

Front

What type of feedback mechanism regulates physiological processes to maintain homeostasis?

Back

Negative Feedback mechanism.

Front

What is the impact of a mutation in the protein components of the transduction signaling pathway?

Back

It alters the response of the cell.

Front

Define Mitosis.

Back

Mitosis is the process of cell division that results in two identical daughter cells.

Front

What are secondary messengers?

Back

Secondary messengers are molecules that relay signals received at receptors on the cell surface to target molecules inside the cell.

Front

Explain the phosphorylation cascade.

Back

A phosphorylation cascade is a series of chemical reactions during cell signaling, where one enzyme phosphorylates another, leading to a chain reaction.

Front

What is the function of ligands in cell signaling?

Back

Ligands are molecules that bind to receptors to initiate a cellular response.

Front

Describe the role of CdK in the cell cycle.

Back

Cyclin-dependent kinases (CdKs) are enzymes that, when activated by cyclins, regulate the progression of the cell cycle.
