Citric Acid Cycle
This enzyme catalyzes the first step of the citric acid cycle, combining oxaloacetate and acetyl-CoA.
What is citrate synthase?
A mutation that changes a codon but does not change the amino acid.
What is a silent mutation?
Gas exchange between the blood and body tissues occurs primarily in these tiny blood vessels that have walls only one cell thick.
What are capillaries?
This molecule serves as the main starting building block for cholesterol synthesis.
What is acetyl-CoA?
A student needs help understanding their financial aid package, paying tuition, requesting transcripts, and resolving registration issues. This UT office serves as the central hub for these services.
What is Texas One Stop?
This regulatory TCA enzyme is activated by ADP and inhibited by ATP and NADH.
What is isocitrate dehydrogenase?
This sequence signals the start of translation in most mRNA transcripts.
What is AUG?
This plant vascular tissue transports water from roots to leaves.
What is xylem?
Most cholesterol synthesis in the body occurs in this organ.
What is the liver?
A student is struggling with anxiety and wants to speak with a counselor. They also want access to mental health services and a 24/7 crisis line. This UT center provides those services.
What is the Counseling and Mental Health Center (CMHC)?
This citric acid cycle intermediate is produced immediately after fumarate.
What is malate?
This type of regulation occurs in the lac operon when lactose disables the repressor.
What is negative regulation?
Two properties of water that help maintain a continuous water column in xylem are these.
What are cohesion and adhesion?
This lipoprotein is the major carrier of cholesterol in the bloodstream and delivers cholesterol to peripheral tissues.
What is LDL (low-density lipoprotein)?
A student is experiencing food insecurity and needs access to free groceries, toiletries, and other basic necessities. This UT program provides those items and additional support resources.
What is the UT Outpost?
This step of the citric acid cycle directly generates GTP through substrate-level phosphorylation.
What is the succinyl-CoA → succinate step (succinyl-CoA synthetase)?
These proteins are required in eukaryotes to initiate transcription along with RNA polymerase.
What are general transcription factors?
In plants, these cells surround stomata and control their opening and closing to regulate gas exchange and water loss.
What are guard cells?
This enzyme catalyzes the committed step of cholesterol synthesis and is heavily regulated.
What is HMG-CoA reductase?
A student wants help exploring career paths, preparing for internships, improving their résumé, and connecting with employers and alumni. This UT office provides career advising, networking opportunities, and professional development resources.
What is Texas Career Engagement?
One turn of the citric acid cycle generates this total number of reduced electron carriers.
What are three NADH and one FADH2?
Place these replication events in the correct order: Topoisomerase, helicase, DNA polymerase, ligase
What is helicase → topoisomerase → DNA polymerase → ligase?
The upward movement of water in xylem is powered by tension generated by transpiration according to this theory.
What is the cohesion–tension theory?
Cholesterol serves as a precursor for these three important molecule classes in the body.
What are steroid hormones, bile salts, and vitamin D?
A student wants a personalized list of tutoring, academic resources, and campus support services based on the courses they are taking. This UT tool provides those recommendations.
What is PEARL (Personalized Academic Resource Locator)?
