Homework Answers
1a. Chromodomain helicase DNA binding protein 3 is a enzyme.
It has a chromatin domain and SNF-2 related helicase ATPase domain.
Chromatic remodelling is essentially for transcription.
Mutation in CHD3 cause a neurodevelopmental syndrome with macrocephaly.
1b. Protein recruits for analysis of protein- protein interaction.
This is used to test interaction between known protein pair and isolation of novel protein interaction.
1c. It regulates G protein, GTPase act as molecular switches and control the function of other protein. They transmit signals by hormones, neurotransmitters and it regulates metabolic enzymes, ion channel , transporter protein.
Hope the answer is clear!! Please please please give positive ratings!! Thank you

1A) Given what you know about cellular respiration, if we were to compare the protein content of the inner and outer mitochondrial membranes, what do you predict we would find? The amount of proteins is equivalent in the outer and inner membranes. The amount of proteins is greater in the outer membrane. The amount of proteins is greater in the inner membrane. 1B) Which of the following statements regarding glycolysis is FALSE? NADPH is produced The reactions do not require...

4. Protein trafficking has been one of the biggest challenges to explore and elucidate in the past few decades. Yet we now know much about this multi-step process. a. What is the fundamental difference between proteins that end up in the lysosomes, plasma membranes, or are secreted from cells versus the group that are exported to, and are incorporated in, the mitochondria and chloroplasts? b. What is the role of the signal sequence and the signal recognition particle (SRP) in...

I just want to see if the answers are right, so for 1a. since
the microtubule is in a cell that's in G0, would there be no
movement since everything stops in G0 phase? Or are the
microtubules continously depolymerizing/polymerizing at a constant
rate?
For 1b. I said the same thing since the cell is in G0 phase then
it wouldn't matter if it was microtubule treadmilling, it wouldn't
be moving.
1c. I'm not sure what exactly would happen

2. Myoglobin (Mb) is one of the most thoroughly studied and best understood proteins. It serves as a model for ligand binding by proteins. Mb is an example of a hemoprotein (a heme containing protein or heme protein) and its ligand is molecular oxygen (O2) which is essential for the survival of aerobic organisms. a. How does an organism benefit from having a protein bind O2? b. Where, specifically, does the ligand bind in Mb? c. Is the heme bound...
