Chapter 6, Problem S1.1BYB
Summary Introduction
To determine:
The relationship between energy and the basic characteristics of life.
Introduction:
The energy is defined as the capacity to perform a task. All the living organism/cells require energy to perform the basic functions of the life.
Expert Solution & Answer
Explanation of Solution
Energy:
The sun is the major source of energy for organisms and the ecosystems. Producers use energy from sunlight to make food. Cells need energy in order to survive. This energy is used to perform functions such as growth, maintaining balance, repair, reproduction, movement, and defense. This means all living organisms must obtain and use energy to live.
There are seven metabolic functions which make difference between living organisms and non-living organisms.
- Respiration Respiration is the release of energy from food substances in all living cells. Living things break down food within their cells to release energy for normal metabolic activity.
- Nutrition Living things take in materials from their surroundings that they use for growth or to provide energy. Nutrition is the process by which organisms obtain energy and raw materials from nutrients such as proteins, carbohydrates, and fats.
- Excretion All living things excrete. As a result of the many
- Growth Growth is seen in all living things. It involves using food to produce new cells. The permanent increase in cell number and size is termed growth.
- Movements All living things follow a specific pattern of movement. This may be observable, such as animals that are able to walk, or less observable, such as tropism in plants. The movement may be so slow, that it is very difficult to see.
- Sensitivity All living things are able to sense and respond to stimuli around them such as light, temperature, water, gravity, and chemical substances.
- Reproductions All living organisms have the ability to produce progeny. Only living organisms possess all of these characteristics.
Conclusion
All living organisms share the basic properties of life that are energy, which categorizes them as living and non-living beings. Energy is needed for the function of movement and standard metabolism.

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.
