Question

11) In a plant cell, DNA may be found (1 pts) O only in the nucleus and chloroplasts only in the nucleus in the nucleus, mitochondria, and chloroplasts in the nucleus, mitochondria, chloroplasts, and peroxisomes 12) You have a cube of modeling Clay in your hands. Which of the following changes to the shape of pts) this cube of clay will decrease its surface area relative to its volume? stretch the cube into a long shoebox shape round the clay up into a sphere flatten the cube into a pancake shape pinch the edges of the cube into small folds (pts) 13) if you were to add one of the eight citric acid cycle intermediates to the culture medium of yeast growing in the laboratory, what do you think would happen to the rates of ATP and carbon dioxide production? The rate of ATP production would decrease, but the rate of carbon dioxide production would increase Rates of ATP and carbon dioxide production would probably both decrease There would be no change in ATP production, but we would observe an increased rate of carbon dioxide production The rates of ATP production and carbon dioxide production would both increase. 14) glucose is the sole energy source, what fraction of the carbon dioxide exhaled by animals is pts generated by the reactions of the citric acid cycle? 1/3 23 1/6 All of 15) A cell with a predominance of tree ribosomes is mostly (pes primarily producing proteins in the cytosol Constructing an extensive cell wall or extrace enlarging its vacuole primary producing protetor secretion

Answer 1

11) In a plant cell ,the DNA is found in the nucleus,mitochondria and in chloroplast.

DNA is the genetic material that is present in all cells,which carries information for structures and to the living things.In the plant kingdom, deoxyribonucleic acid is with in the membrane bound cell structure of nucleus chloroplast and in mitochondria.

12)The following changes to the shape of this cube of clay will decrease its surface are relative to its volume is the round the clay up into a sphere.

13) If add one of the 8 citric acid cycle intermediate to the culture medium of yeast growing in the laboratory.The rates of ATP production and carbon dioxide production both will increase.

The citric acid cycle does nit produce ATP directly,it makes ATP indirectly through NADH and FADH2.The electron carriers deposit in the electron transport chain to synthesis ATP.

14)The glucose is the sole energy,2/3 fraction of the carbondioxide exhaled by the animals is generated only when the reaction involved in the oxidation of pyruvate to acetyl CoA.

15) A cell with predominance of free ribosomes is most likely by producing primarily cytoplasmic proteins in the cytosol.

Ribososmes are small structure that function in synthezing of proteins. That proteins are essential for catalyzing the metabolic reactions and protecting against from infections. They are two types of ribosomes which are free and membrane bound in which membrane bound ribosomes produce proteins that are exported from the cell to be used and whereas free ribosomes produce proteins inside the cell.
