Which of the following is true about transcription factors? They regulate the synthesis of DNA in response to a signal. o They are needed to regulate the synthesis of a protein in the cytoplasm. They control which genes are turned on to form mRNA. O They block the mRNA from being translated. Kinases along the signal transduction pathway are often activated via o phosphorylation by ATP O dephosphorylation by ADP

D Question 9 0.59 pts 2 mM ATP 5 3- C21 nM AMPK-AMP Kinase Which of the following best explains what is happening in this graph? e There is a negative correlation between substrate concentration and AMPK activity. ATP acts as an allosteric activator when concentration of substrate is at least 10 nM. AMPK is not active without the presence of the substrate at 10 nM or greater concentration.

Welcome to our plant sciences department here at TransBiol It's great to have you as an intern. I'm the lead scientist of a team developing new herbicides to use against invasive plant species. The team has been really swamped with work, so it'll be great to have some help analyzing all the data we're collecting. Since it's your first day, a great way to get started with any research project is to brush up on the background knowledge you'll need...

Prelab Activity:
Electrochemical Cells
To determine the solubility product of copper(II) carbonate,
CuCO3 , a concentration cell as described on pages 71-72
of the lab handout is constructed. The temperature of the Galvanic
cell is measured to be 22.5°C, and the cell potential 282 mV (0.282
V). Using this data and Equation 8 in the lab manual, calculate the
Ksp for CuCO3 and report your answer with
three significant digits.
For the Galvanic cell you will construct in PART B,...
