Can someone help me out?? 1. The synthesis of glucose from smaller precursors is called: a) gluconeogenesis. b) glycogenolysis. c) glucosynthesis. d) glycolysis. e) none of the above I think the answer is A. gluconeogenesis...because gluconeogenesis is from puruvate back to...

I have some questions that i am not sure...can u guys help me out ? 1. Which of the following is the best phrase to describe the modern view of membrane structure? a. Membranes are lipid-lipid bilayers. b. Membranes are lipid-lipid bilayers with associated proteins. c. Membranes are...

Hey guys, can somebody helps me to understand better about fibrous vs globular protein please "So what is the main difference between fibrous proteins and globular proteins? Aside from the difference in shape (elongated vs. spheroidal) and solubility (insoluble vs. soluble), fibrous proteins...

Ionic Strength...help I am taking Biochemistry. However, the prof talked about Inoic Strength in class. This is the example, u = 1/2 (Molarity) (ionic charge )^2 Example... .10M CaCl2 u = 1/2 (.10)(+2)^2 + (.20)(-1) ^2 u = 1/2 ( .40 + .20 ) = .30 I opened my Chemistry...

I can't find the answer on the net..if anyone taken cell bio. Can you guys help me out :) 1. how does the structure of fucus differ from the green algae? 2. how is a holdfast different from a plant root? 3. consifering where fucus lives, what do you think is the function of its air...

Thank you :) problem solved :) yeehaaa :)

Bomba923, What is the final pH when 100 ML of .5M HCL is added to 900 mL of water? A. 1.3 B. 5.0 C. 13.0 D. .5 D. none of the above I didn't see pH = 1 ...is it None of the above?? :( hihihi I didn't see

Bomba, Thank you! cAN SOMEONE help me to check my PH cal please :) 1. The pH of .55M aqueous solution of hypobromous acid, HBrO, at 25celcius is 4.45. What is the vale of Ka for HBrO? HBr0 + h20 = H30+ + BRO- Ph= - log (H+) 4.48 = -log (H+) H+ = .00003 Ka =...

Bomba, I think the answer is all of the above. But when i read the question again..he asked " MOST IMPORTANT BUFFERING SYSTEM " then i think it's only Bicarbonate..blood is extracelluar has PKA around 6.1 that close to Blood PH...on the other hand, phosphate is only for intracelluar...

Bomba, Blood is around 7.4. But all of the PKA from A, B, and C are closed to 74...is it ALL OF THE ABOVE??

Dear Bomba, Kushal, and Ismith, I have another question The most important buffering system for maintain proper blood PH is A. charge on the amino acid B. the bicarbonate buffer system of Co2, carbonic acid and bicarbonate C. Phosphate groups of serum phosphorproteins D. all of the...

iansmith, ribosome is used for protein synthesis. But bacteria = prokaryotes...ribosome and mitochondria are eukaryotes. I think E is the right anwer.

thanks Kushal, I have one more question to ask u which of the following accurately lists the proper for these cells compentets in increasing size?? A. protein, proton, ribosome, mitochondira, bacteria...... : B. proton, protein, mitochondria, ribosome, bacteria C. proton, protein...

4. The enzyme reverse transciptase is critical for? A. converting the RNA genome of a virus into the DNA form of the host cell. B. converting the RNA genome of a bacterium into the doble stranded RNA form. C. replacig the uracil with the thymine in DNA strands. D. replacing the broken...
