Summary Introduction

Introduction:

Prokaryotes are mostly unicellular organisms and are divided into two domains, which are bacteria and archaea. They do not have membrane-bound organelles. The prokaryotic nucleus is not surrounded by the nuclear membrane and also lacks mitochondria.

Answer to Problem 1TYK

Correct answer:

The food energy is converted into chemical energy (ATP) in the plasma membrane of the prokaryotes.

Explanation of Solution

Justification for the correct answer:

Option (e) is plasma membrane. This is true as the plasma membrane metabolizes food molecules into the chemical energy. The plasma membrane of the prokaryotes constitutes some specialized molecules, which uses the food molecules and convert them into ATP (adenosine triphosphate). ATP is the energy currency of the cell and provides energy for various metabolic reactions. Hence, option (e) is correct.

Justification for the incorrect answers:

Option (a) is chromosome. This is false as the chromosome contains the genetic material DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). The genetic material encodes the information which is required for the formation of protein. It does not convert food energy. It is simply passed on from one generation to the next. So, it is an incorrect option.

Option (b) is flagella. This statement is incorrect as the flagella uses the ATP (adenosine triphosphate) for the propelling movement and, thus, for locomotion. It is not involved in the formation of the ATP. So, it is an incorrect option.

Option (c) is ribosomes. This is incorrect because the ribosomes are involved in the conversion of the genetic information from DNA (deoxyribonucleic acid) to mRNA (messenger ribonucleic acid). The prokaryotic ribosomes consist of large and small subunits. It does not involve the generation of the ATP molecule. So, it is an incorrect option.

Option (d) is cell wall. This is incorrect because the cell wall provides protection and rigidity to the cell. It protects the cell from mechanical damage and, also, from the harsh conditions of the environment. So, it is an incorrect option.

Hence, options (a), (b), (c), and (d) are incorrect.

Conclusion

Thus, it can be concluded that the plasma membrane has a specialized molecular system and these molecular systems are responsible for the conversion of food energy into ATP (adenosine triphosphate).

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…

This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
