Question 1

Appeared in Year: 2016 (IFS)

Describe in Detail Subjectiveâ–ľ

How is cell signal transduction effected?

Edit

Explanation

Signal Transduction

  • A process by which chemical or physical signal is transmitted through cell.
  • A series of molecules events which cause cellular response.
  • Proteins are responsible for detecting stimuli. They are called receptors.
  • Changes occur when ligand bind to receptor.
  • These changes give rise to chain of biochemical events called signalling pathway…

Question 2

Appeared in Year: 2018

Describe in Detail Subjectiveâ–ľ

Discuss the role of cyclin-dependent protein kinases in controlling the cell cycle with the help of a diagram

Edit

Explanation

Cyclin-dependent kinases (CDKs) are serine/threonine protein kinases that play important roles in tumour cell proliferation and growth by modulating cell cycle, transcription, and RNA splicing. Furthermore, some CDKs have numerous substrates and phosphorylate transcription factors that are implicated in carcinogenesis.

Process of Cell Regulation
  • CDKs…

Question 3

Appeared in Year: 2021

Describe in Detail Subjectiveâ–ľ

Explain the process of cell signalling highlighting the role of various signalling molecules.

Edit

Explanation

Cell Signalling

Cell signalling is the process through which cells interact with one another or with their surroundings. Cell signalling takes place via multiple unique mechanisms. Cell signalling is required for multicellular organisms to control several processes. For example, nerve cells work in tandem with muscle cells to aid in bodily movement.…

Question 4

Appeared in Year: 2021 (IFS)

Describe in Detail Subjectiveâ–ľ

Write a note on: Cell signaling (Paper 2)

Edit

Explanation

  • Cell signaling is the mechanism through which cells interact with other cells within the body or with the outside world. Multiple different routes contribute to cell signaling. Cell signaling is necessary for multicellular organisms to govern several processes. For instance, nerve cells communicate with muscle cells to facilitate bodily movement. I…

Appeared in Year: 2020 (IFS)

Describe in Detail Subjectiveâ–ľ

What are autocrine, paracrine and endocrine types of intercellular signaling? (Paper-2)

Edit

Explanation

The term “intercellular signaling” refers to the communication that takes place between the cells of an organism that is composed of more than one cell. Intercellular communication may take place in a number of different ways, the most prevalent of which are autocrine signaling, paracrine signaling, and endocrine signaling. An explanation of each k…

Describe in Detail Subjectiveâ–ľ

Write short notes on the following: Heat shock proteins and their functions (Paper 2)

Edit

Explanation

Heat Shock Proteins (HSPs)

Ans. Heat shock proteins (HSPs) are a group of proteins that are synthesized in response to cellular stress, particularly exposure to elevated temperatures. However, these proteins can also be induced by various other stressors, such as oxidative stress, toxins, infections, and inflammation. The main function of heat shock…
