Indicate the Various Points Along the Cellular Respiration Pathway That These Molecules Can Enter. The amino acids from proteins and the glycerol and fatty acids from fats can be "burned" to yield ATP using the cellular respiration pathways. However, these nutrient molecules do not go through glycolysis first. Indicate the various points along the cellular respiration pathway that these molecules can enter (Check all that apply).

Payday lenders are firms that make short-term (often one- to two-week) loans to consumers. The intent is to provide households with some extra cash in advance of the next paycheck. An example of such a lender is Check 'n Go (https://www.checkngo.com). The loan terms of these loans are attached on the last page of this problem set. According to the loan terms of Check 'n Go, if you obtain a two-week loan of $500, in two weeks (i.e., 14 days), you have to repay $555.00. (a) What is your two-week interest charge expressed as a percentage of the loan received? (i.e., your periodic interest rate over the 14-day period)? (b) If the interest is compounded every 14 days, how many compounding periods do you have in one year (assuming 365 days in a year)? Using this number of compounding periods and the periodic rate for the 14-day loan you found in (a), show how Check 'n Go arrived at the APR that the firm reported for the $500 loan. (c) Using the number of compounding periods and the APR that you found in (b), find the Effective Annual Rate (EAR) on this borrower-friendly loan. As in (b), interest is compounded every 14 days and there are 365 days in a year. Why is this rate higher/lower than APR? (d) Suppose Check 'n Go charges the same APR as it does right now for a $500 loan, but changes its compounding frequency to daily. Assuming daily compounding (365 days in a year) and the APR stated in (b), what would be the EAR on this loan? ANNUAL PERCENTAGE RATE The cost of your credit as a yearly rate (Assumes a 14-day term) FINANCE AMOUNT FINANCED CHARGE The amount we pay to you The dollar amount the credit or on your behalf will cost you TOTAL OF PAYMENTS The amount you will have paid after you have made all payments as scheduled NUMBER OF PAYMENTS 521.43% 434.52% 391.07% 365.00% 347.62% 335.20% 325.89% 318.65% 312.86% 308.12% 304.17% 300.82% 297.96% 295.48% 293.30% 291.39% 289.68% 288.16% 286.79% $10.00 $12.50 $15.00 $17.50 $20.00 $22.50 $25.00 $27.50 $30.00 $32.50 $35.00 $37.50 $40.00 $42.50 $45.00 $47.50 $50.00 $52.50 $55.00 $50.00 $75.00 $100.00 $125.00 $150.00 $175.00 $200.00 $225.00 $250.00 $275.00 $300.00 $325.00 $350.00 $375.00 $400.00 $425.00 $450.00 $475.00 $500.00 $60.00 $87.50 $115.00 $142.50 $170.00 $197.50 $225.00 $252.50 $280.00 $307.50 $335.00 $362.50 $390.00 $417.50 $445.00 $472.50 $500.00 $527.50 $555.50 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
