10.1Q1 Define three stages of the cell cycle? Correct Answer-Interphase G0: where cells rest G1: where cells grow and expand S: where DNA is replicated G2: where cells repair damaged DNA and duplicate centrosomes Cell division (M) phase Where cells undergo nuclear and cytoplasmic division 10.2Q1 What are cyclin-dependent kinases (Cdks)? Correct Answer-A small family of protein kinases that regulate the transition of various phases in the cell cycle. CDKs are small proteins that mainl...

Lipinski's rule of 5 - ANSWER-- Poor absorption or permeation are more likely when: 1. mass greater than 500 Da 2. highly lipophilic - logP > 5 3. more than 5 hydrogen bond donors 4. more than 10 hydrogen bond acceptors Partition coefficient - ANSWER-p = C(octanol)/C(water) - ratio of the equilibrium concentrations of dissolved substance in a two-phase system containing two largely immiscible solvents (water & octanol) - Log10(P) Improved Lipinski Parameters - ANSWER-1. Partition...

Lecture notes for the Cancer Pharmacology section of module LIFE 206 - Drug Action. Provides an overview of: What is cancer, what causes cancer, challenges facing cancer therapy, evaluation of cancer drugs, targeted therapy, protein kinases (example BCR-ABL tyrosine kinase/CML/Imatinib), EGFR tyrosine kinase, and apoptosis pathways. Also includes 50 example exam question/answers.

Gastric acid secretion by parietal cells of the gastric mucosa are stimulated by - ANSWER *acetycholine, histamine, gastrin Receptor-mediated binding of acetylcholine, histamine, or gastrin results in - ANSWER *the activation of protein kinases, which in turn stimulates the H+/K+-adenosine triphosphatase (ATPase) proton pump Gastrin and acetylcholine stimulate release of - ANSWER histamine

APHY 102 Midterm-ivytech Exam Questions and Answers What is a hormone and how does it act? Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. Understand the role of negative feedback in control of hormone secretions A control mechanism in which rising level of a hormone leads to a decrease in hormone ...
