1. Which statement regarding the sodium-potassium pump is correct? 1. The cell’s plasma membrane is more soluble to sodium ions than potassium ions. 2. The concentration of sodium ions should be higher inside the cell compartment. 3. The concentration of potassium ions should be higher outside the cell compartment. 4. The active transport involves pumping out three sodium ions and pumping in two potassium ions. 2. What is the process in which glucose is used to create energy? 1. Autol...

Purines and examples of them Purines contain two carbon-nitrogen rings and four nitrogen atoms. Adenine and guanine Pyrimidines and examples of them pyrimidines contain one carbon-nitrogen ring and two nitrogen atoms. Thymine and cytosine Structure of DNA DNA is a double helix (two helical strands.) The two strands are held together by the 'rungs', which are made of complementary pairs. The pairs are held together by weak hydrogen bonds. Arrangement of DNA antiparallel arrangement, ...
