Answer 1

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Introduction: The genetic material of the cell passes on the hereditary information from the parent to offspring.

B.

Summary Introduction

To examine: Whether the statement “Bacterial DNA is found in the cytosol” is correct or incorrect.

Introduction: The cytosol is an aqueous medium in which the membrane-bound organelles float in eukaryotic organisms having the chemical composition of water, dissolved ions, polar molecules and proteins. In prokaryotes, they are the site of action of chemical reactions associated with cell metabolism.

C.

Summary Introduction

To examine: Whether the statement “plants are composed of prokaryotic cells” is correct or not.

Introduction: Cells are of two types: prokaryotic and eukaryotic cells. Prokaryotic cells are primitive; lack membrane bound cell organelles and a nucleus. The genetic material is present in the cytosol.

D.

Summary Introduction

To explain: Whether the statement “With the exception of egg and sperm cells, all of the nucleated cells within a single multicellular organism have the same number of chromosomes” is correct or incorrect.

Introduction: Both prokaryotes and eukaryotes have chromosomes which make up the genetic material of an organism. Chromosomes are thin, thread-like structures visible at the time of cell division. They are DNA in compacted form, held together by basic proteins called Histones. The chromosome number varies between the somatic and sex cells. The somatic cells have 2n number and sex cells have n number of chromosomes. The chromosome number remains the same for a single species, and they vary greatly between species.

E.

Summary Introduction

To explain: Whether the statement “The cytosol includes membrane-enclosed organelles, such as lysosomes” is correct or incorrect.

Introduction: Lysosomes are minute, single-membrane-bound organelles that perform the function of intracellular digestion and degradation of molecules for recycling within the cell or for cellular level excretion. They are the site of degradation of large and small molecules.

F.

Summary Introduction

To explain: Whether the statement “The nucleus and mitochondria are surrounded by a double membrane” is correct or not.

Introduction: Nucleus and mitochondria are cell organelles found in the cytosol of eukaryotic cells.

G.

Summary Introduction

To explain: Whether the statement “Protozoans are complex organisms with a set of specialized cells that form tissues, such as flagella, mouthparts, stinging darts, and leglike appendages” is correct or not.

Introduction: Protozoans are eukaryotic organisms that are unicellular.

H.

Summary Introduction

To explain: Whether the statement “Lysosomes and peroxisomes are the sites of degradation of unwanted materials is correct or not.

Introduction: Peroxisomes are minute, single-membrane-bound vesicles that give a safe reaction site for reactive oxygen species or oxy radicals such as H₂O₂ and other toxic radicals.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
