Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.

Discuss the role of target proteins in the signal transduction pathway and provide an example.
How does the specificity of receptor-ligand interactions influence the outcome of signal transduction?
Describe a scenario where a malfunction in a signal transduction pathway could lead to disease.
Describe the process of reception in a signal transduction pathway and explain its significance.
Explain the process of transduction in a signal transduction pathway and its importance in cellular communication.
Describe the response phase in a signal transduction pathway and provide an example of a cellular response.
How does the amplification of a signal during the transduction phase benefit the cell?
What role do second messengers play in the transduction phase of a signal transduction pathway?
Discuss the role of protein kinases in the signal transduction pathway.
(Student response here)
Protein kinases play a pivotal role in signal transduction pathways by transferring phosphate groups from ATP to specific proteins, a process known as phosphorylation. This modification can activate or deactivate proteins, thereby regulating their function. Protein kinases often act in a cascade, where one kinase activates another, amplifying the signal and leading to a precise and coordinated cellular response. This phosphorylation cascade is essential for processes such as cell division, metabolism, and apoptosis.
What is the primary function of protein kinases in signal transduction pathways?
To transport signal molecules across the cell membrane.
To synthesize new proteins.
To degrade signal molecules.
To phosphorylate proteins, thereby regulating their activity.
