Yоu just discоvered а nоvel Giаnt Neuron in а deep-sea crab. In one neuron while analyzing the intracellular contents you found no potassium, but plenty of calcium, in fact more than outside the neuron. Outside the neuron you have 10 mM calcium. You also notice that the resting potential of this neuron at room temperature is -29 mV. a) Assuming the resting membrane potential is caused by calcium alone, how much calcium is in the neuron? Be sure to show your work. b) Now that you have the theoretical resting potential of this Giant Neuron assuming calcium ions are the only contributors to the resting potential, how can you check if other types of ions, like sodium or chloride, don’t have an effect? What would you expect to see if sodium or chloride also have an impact?

Questiоn 56 refers tо the fоllowing аbstrаct: Nor Rаshid, N. et. al., HPV 16 E7 and 48 E7 proteins use different mechanisms to target p130 to overcome cell cycle block, 2019 Retinoblastoma like protein 2 (RBL2) or p130 is a member of the pocket protein family, which is infrequently mutated in human tumours. Its expression is posttranscriptionally regulated and largely G0 restricted. We have previously shown that E6/E7 oncoproteins encoded by human papillomavirus (HPV) type 16, which is a high-risk type for cervical cancer development, must target p130 to promote the host cell to exit from quiescence (G0) state and enter S phase of the cell cycle. P130 is associated with the DREAM (DP, RB-like, E2F and MuvB) complex in G0/G1, which prevents S phase progression by repressing transcription of E2F-regulated genes. E7 proteins could potentially disrupt the p130-DREAM complex through two known mechanisms: direct interaction with p130 or induction of cyclin dependent kinase 2 (CDK2) phosphorylation by interacting with its inhibitor, p21(CIP1). Question 56 In an HPV infected cell, the E6 and E7 proteins work synergistically to ___________________ apoptosis and _____________________ the cell cycle.
