cell communication
What molecule is used in long distance cell communication?
what is hormones
which hormone is directly involved in the regulation of blood glucose levels and is secreted by the pancreas?
What is insulin
What is the outcome of cytokinesis in mitosis?
What is two identical daughter cells
True or false does positive feedback enhance or trigger stimulus?
what is true
what are control points that ensure accurate replication and division, and preventing errors called in the cell cycle?
What is cell cycle checkpoints?
How do cells communicate over short distances?
what is paracine signaling
Which reaction does a kinase catalyze in a signal transduction pathway?
What is phosphorylation of a target protein
Prophase, metaphase, anaphase, and telophase occur in this phase of the cell cycle
What is M-phase?
Child birth, blood clotting, and fruit ripening are examples of positive or negative feedback?
What is positive feedback?
Which checkpoint ensures that DNA has been replicated correctly before the cell enters mitosis
What is G2 checkpoint
What type of contact do cells communicate to each other through?
What is direct or indirect contact
Changes in gene expression, protein synthesis, cell growth, cell divisions, changes in cell metabolism, and cell migration are examples of which pathway
What is a signal transduction pathway
what phase does the cell go into where the cell is neither dividing nor preparing for division?
What is G0 phase?
The two types of feedback systems that help organisms maintain homeostasis are?
what is positive and negative feedback
True or false...Checkpoints occur in G1, S phase, G2, and M phase of the cell cycle?
What is true
What signaling occurs when a cell target a nearby cell?
what is paracrine signaling
What else could interfere with proper functioning of the pathway?
What is transcription factor
What type of cells use mitosis in the M-phase of the cell cycle?
What is somatic cells (body cells)
Regulation of body temperature, blood sugar, and blood pH are examples of which type of feedback?
What is negative feedback
What happens if a cell cycle checkpoint fails?
What is accumulation of genetic errors, potentially leading to cancer
Reception, transduction, and response are the three stages in what cell communication process?
what is the cell signaling process
Altered function of the component, complete loss of function, or cell death happens if the protein or DNA sequence is?
What is mutated
Name the cell division concerned with cancer?
what type of feedback do we use to perform tasks that take us away from homeostasis (like childbirth)?
what is positive feedback
What enzymes control the progression of cells through the cell cycle checkpoints?
What is Cyclins and cyclin-dependent kinases (CDKs)
