Chapter 20.2, Problem 4CC
Summary Introduction
Sulfolobus is one of the best-studied members of Crenarchaeota. Sulfolobus members are spherical, aerobic, and irregularly lobed. They can thrive in a temperature optimum of about 80 ̊ C and the pH optimum of 2-3. Thus, they are referred to as thermoacidophiles. Under oxic conditions, Sulfolobus species able to grow chemoorganotrophically and also grow chemolithoautotrophically, consuming H2S, H2, and FeS2 as electron donors and consuming oxygen as the terminal electron acceptor (though the use of ferric iron has been reported). Sulfolobus species use HP/HB cycle when growing chemolithoautotrophically and when growing chemoorganotrophically, they use the Entner-Doudoroff pathway (nonphosphorylative version), and tricarboxylic acid cycle (TCA).

Problem 1 (Mental Health): The survivor victim is dealing with acute stress and symptoms of a
post-traumatic stress disorder (PTSD) due to their traumatic experience during the January 2025 wildfire.
Goal 1: To alleviate the client's overall level, frequency, and intensity of
anxiety and PTSD symptoms so that daily functioning remains
unimpaired.
Objective 1: The client will learn and regularly use at least two anxieties
management techniques to reduce anxiety symptoms to less than three episodes per week.
Intervention 1: The therapist will provide psychoeducation about anxiety and
PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant).

Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
