QUESTION 14

1. 445 moles of NADH are produced by the Citric Acid Cycle (CAC). How many moles of glucose needed to be broken down during glycolysis in order to produce enough pyruvate for the CAC to produce this many moles of NADH?

   Note: Brock, a Biology of Microorganisms considers the synthesis of Acetyl-CoA to be part of the Citric Acid Cycle. This is different than what you may have learned in BIOL-151 where the Morris Book considers Acetyl Co-A Synthesis a seperate step. See page 89 of Brock for full details.

   Round your answer to one decimal place.

QUESTION 15

1. If 82 moles of ATP are produced by glycolysis, how many moles of glucose were broken down?

   For every molecule of glucose broken down, 2 molecules of ATP are generated.

QUESTION 16

1. NADH and FADH are produced by the Citric Acid Cycle (CAC) and these electron shuttles go on to the Electron Transport Chain (ETC). A mole of NADH will produce 3 moles of ATP from the ETC. A mole of FADH₂ will produce 2 moles of ATP from the electron transport chain. A single mole of pyruvate will produce 4 moles of NADH and 1 mole of FADH2 from the CAC. Therefore, every  14 moles of ATP came from 1 mole of pyruvate.

   Given:

   The ETC produced 78 moles of ATP from the products of the CAC.

   Find:

   How many moles of pyruvate entered the CAC?

   Note: Brock, a Biology of Microorganisms considers the synthesis of Acetyl CoA from Pyruvate to be part of the Citric Acid Cycle. This is different than what you may have learned in BIOL-151 where the Morris Book considers Acetyl Co-A Synthesis a separate step. See page 89 of Brock for full details.

   Round your answer to one decimal place.

Break-Even Sales Under Present and Proposed Conditions

Darby Company, operating at full capacity, sold 156,100 units at a price of $108 per unit during the current year. Its income statement is as follows:

The division of costs between variable and fixed is as follows:

Management is considering a plant expansion program for the following year that will permit an increase of $1,296,000 in yearly sales. The expansion will increase fixed costs by $172,800, but will not affect the relationship between sales and variable costs.

Required:

1. Determine the total variable costs and the total fixed costs for the current year.

2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year.

3. Compute the break-even sales (units) for the current year.
units

4. Compute the break-even sales (units) under the proposed program for the following year.
units

5. Determine the amount of sales (units) that would be necessary under the proposed program to realize the $6,094,800 of income from operations that was earned in the current year.
units

6. Determine the maximum income from operations possible with the expanded plant.
$

7. If the proposal is accepted and sales remain at the current level, what will the income or loss from operations be for the following year?
$

8. Based on the data given, would you recommend accepting the proposal?

1. In favor of the proposal because of the reduction in break-even point.
2. In favor of the proposal because of the possibility of increasing income from operations.
3. In favor of the proposal because of the increase in break-even point.
4. Reject the proposal because if future sales remain at the current level, the income from operations will increase.
5. Reject the proposal because the sales necessary to maintain the current income from operations would be below the current year sales.

Choose the correct answer.

Port Ormond Carpet Company manufactures carpets. Fiber is placed in process in the Spinning Department, where it is spun into yarn. The output of the Spinning Department is transferred to the Tufting Department, where carpet backing is added at the beginning of the process and the process is completed. On January 1, Port Ormond Carpet Company had the following inventories:

Departmental accounts are maintained for factory overhead, and both have zero balances on January 1. Manufacturing operations for January are summarized as follows:

Total Cost Method of Product Pricing

Compare the elasticity of a monopolistic competitor’s demand with that of a pure competitor and a pure monopolist. Assuming identical long-run costs, compare the prices and outputs that would result in the long run under pure competition and under monopolistic competition. Contrast the two market structures in terms of productive and allocative efficiency. Explain: “Monopolistically competitive industries are populated by too many firms, each of which produces too little.”

Labor Variances Cinturon Corporation produces high-quality leather belts. The company's plant in Boise uses a standard costing system and has set the following standards for materials and labor: Leather (3 strips @ $4) $12.00 Direct labor (0.75 hr. @ $12) 9.00 Total prime cost $21.00 During the first month of the year, the Boise plant produced 92,000 belts. Actual leather purchased was 287,500 strips at $3.90 per strip. There were no beginning or ending inventories of leather. Actual direct labor was 78,600 hours at $12.50 per hour.

Required: 1. Break down the total variance for labor into a rate variance and an efficiency variance using the columnar and formula approaches.

Rate variance $ 39,300

Unfavorable Efficiency variance $ 46,000 Unfavorable ??????

Total variance $ -276,900 Unfavorable ????

2. CONCEPTUAL CONNECTION As part of the investigation of the unfavorable variances, the plant manager interviews the production manager. The production manager complains strongly about the quality of the leather strips. He indicates that the strips are of lower quality than usual and that workers have to be more careful to avoid a belt with cracks and more time is required. Also, even with extra care, many belts have to be discarded and new ones produced to replace the rejects. This replacement work has also produced some overtime demands. What corrective action should the plant manager take? Return to suppliers that provide the quality corresponding to the price standard. Employ more skilled labor at a cost lesser than the savings made by buying cheap material and improve the product quality. There is no need to change anything. The sales are not affected by this low quality of raw material.
