Concept explainers
a.
A transcription factor is a protein that controls the degree of genetic information transcription from DNA to messenger RNA (mRNA) through binding to a particular DNA sequence. The essential function of the transcription factor is to regulate (turn off or turn on) the genes in order to ensure that they are expressed in an exact cell at an exact time and exact amount throughout the life.

In one of the reactions of the citric acid cycle, malate is oxidized to oxaloacetate. When this reaction is considered in isolation, a small amount of malate remains and is not oxidized. The best term to explain this is a. enthalpy b. entropy c. equilibrium d. free energy e. loss of energyarrow_forward

OA. TIM22 OB. TIM23 C. OXA OD. Mia40 OE SAMarrow_forwardQUESTION 9 An animal cell has been wounded and has a small rupture in its plasma membrane. Which of the following is more likely to happen next? OA. The cell rapidly cleaves by cytokinesis. OB. The rate of receptor-mediati endocytosis is increased. OC. The rate of exocytosis is increased. OD. The rate of pinocytosis is increased.arrow_forwardFor the a subunit of a trimeric G protein, A. a G-protein-coupled receptor GPCR) acts as a guanine nucleotide exchange factor (GEF), whereas a regulator of G protein signaling (RGS) can act as a GTPase-activating protein (GAP). B. a GPCR acts as a GAP, whereas an RGS can act as a GEF. C. both a GPCR and an RGS can act as a GEF. O D. both a GPCR and an RGS can act as a GAP OE. None of the above.arrow_forward
- A cell expresses a transmembrane protein that is cleaved at the plasma membrane to release an extracellular fragment. The fragment binds to receptor proteins on nearby cells and activates signaling pathways resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent? OA. Contact-dependent signaling B. Paracrine signaling OC. Synaptic signaling D. Endocrine signaling E. Autocrine signalingarrow_forwardWhich of the following drive nuclearly encoded proteins import into the mitochondrial matrix? OA. ATP hydrolysis OB. Membrane Potential OC. K+ Ions OD. A and B OE.
