Question 9 of 400.0/ 2.5 PointsWhat statement describes protein phosphorylation?A. cyclic AMP is an inhibitor of protein kinase AB. serine is often phosphorylatedC. dephosphorylation occurs when ATP is regeneratedD. phosphatase catalyzes a transfer of a phosphate
Feedback:Learning Objective: Recognize the role of phosphorylation in the transmission of intracellular signalsQuestion 10 of 40
2.5/ 2.5 PointsAlmost all life cycles will have haploid and diploid phases. The transition from haploid to diploid occurs
Feedback:CorrectQuestion 11 of 402.5/ 2.5 PointsMature cardiac cells remain metabolically active but do not proliferate. This type of arrest is known as the _________.
PhaseFeedback:CorrectQuestion 12 of 402.5/ 2.5 PointsA newly-discovered butterfly species has a chromosome number of n=7. Match the total number of chromosomes in each type of cell.A. 14B. 71. Zygote2. Daughter cell after telophase IIFeedback:The gamete is haploid (7), the zygote is the diploid embryo (14), somatic cells are diploid (14) and after telophase II the daughter cells are haploid (7).Question 13 of 400.0/ 2.5 PointsIn vertebrate immune systems, some t-lymphocytes will make a growth factor that drives their own division. This represents
AB
Feedback:Incorrect:Learning Objective Text: Describe four types of signaling found in multicellular organismsQuestion 14 of 402.5/ 2.5 PointsCancer is caused by unregulated cell growth. One way to attack cancer cells is to harness the power of signaling pathways. For each type of drug, match it to the component of the pathway it would bind to.A. ribosomeB. kinaseC. G proteinD. cell surface receptorE. transcription factor1. A drug that mimics an extracellular growth signal ________2. A drug that blocks GTPase activity ________3. A specific kinase inhibitor ________4. A drug that interferes with transcription of certain genes ________5. A drug that blocks translation completely ________Feedback:CorrectQuestion 15 of 402.5/ 2.5 PointsMolecules generated from butter will enter aerobic cellular respiration atDCBEA
