d What phospholipid bilayer to disassemble (1pt) sort of environment would cause the 4 You performn an esperiment using a certain type of single celled reproduction depends on the amount of energy they get from their food. More nrgy results in faster reproduction. You provide "colony A" with saturated fatty containing 22 carbons. You provide colony B" with 22-carbon polyunsaturat acds You provide "Colony C" with starch. Each colony gets exactly.05 grams of its nutrient daily Each colony starts off with 100,000 cells. Cells are equally able to use any of these 3 nutrients (each black is worth 1 point) organism, where rate Which colony ("A", 'W, or "C") is being provided with the most bAfter 48 hours, which colony would have the fewest cells? -Explanation / Answer
4) The energy is obtained from the electrons donated by the hydrogen atoms present in the food. The number of Hydrogen atoms present per gram of a carbohydrate is lesser than the number of hydrogen atoms present in a fatty acid. (this is because there is an additional mass of n number of O atoms in carbohydrates(Cn(H2O)n) which is absent in fatty acids). Since starch is a carbohydrate, it will have lesser hydrogen atoms per gram when compared with both the fatty acids (saturated and polyunsaturated). Now, when we come to saturated and unsaturated fatty acids, obviously the saturated fatty acids will have more number of hydrogen atoms. Therefore, more energy will be derieved from the saturated fatty acid than from the starch or from the unsaturated fatty acid.
a) The colony A will be provided with most calories because they are being fed with saturated fatty acids.
b) The colony C will have the least number of cells as they are being fed up on starch and hence, they have lesser number of hydrogen atoms per gram for the electron transfer and therefore lessser energy for reproduction.
