Question

c. Which solution contains an amino acid other than proline? 7. What are some good sources of carbohydrates, proteins, and fats in a typical breakfast, lunch, and dinner? Four known amino acids (Ad) produce a chromatograph with Ry values as follows: AA, 0.25, AA2 a 0.66 AA, = 0.50, A4-0.80. A mixture of three anino acids yields spots that are 2 cm, 5.2 cm, and 6.4 cm from the origin. The solvent front is 8.0 cm from the origin. Which three of the four amino 8. acids are contained in the mixture? In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluid because they cannot be stacked closely together. Of what advantage would this be for herbaceous plants that live through the winter? (Hint: what happens to bacon grease or the grease on top of soup when you put it in the refrigerator?) 9. WORKSHEET

Explanation / Answer

7. BREAKFAST-

Carbohydrates- juice, bread,cornflakes milk., fruits

Proteins- Egg, chicken, meat, milk, banana

Fats- butter, meat, etc

Lunch- carbohydrates- rice, chapati

proteins- curd, fish

fats- meat, chicken, fried food ,cheese

Dinner-  carbohydrates- rice, chapati, vegetables

proteins- fish, egg, lentils, pulses

fats- meat, cheese

8. Rf is calculated by the distance moved by the solute / distance moved by the solvent.

2/8= 0.25

5.2/8= 0.65

6.4/8= 0.8

So, the mixture contains AA1, AA2, and AA4.

9. Herbaceous plants become hard in winter. It provides mechanical strength and flexibility to the plants.
