| Q. | For Professor Jay? | Related Search: Biology | | | I know you're a very busy Professor, but I would greatly appreciate the professional help for my midterm ( university of course) I totally understand if you don't have the time. Thanks
And for others that can explain this to me.. Very welcome.. Thank you to all.
Why does the cell have checkpoints in the cell cycle? Name one. ( this one is quite important.. i dont really understand how the cell cycle does.. like why is it soo important...)
Why do many molecules not break down rapidly into smaller molecules, even when it is energetically favorable?
Where do competitive inhibitors of enzymes bind?
Why would a cell prefer respiration over fermentation?
What is alternative splicing?
Thanks guys :)
| | A. | The cell cycle has checkpoints at every stage. The checkpoints just make sure that everything is progressing normally. Here are a couple of examples of checkpoints.
1. DNA damage checkpoint - makes sure that the DNA is intact and undamaged.
2. The G1 checkpoint, or restriction checkpoint - at the end of the G1 stage of interphase - determines if the cell will stay in that stage or continue on in the cell cycle. If a cell is going to continue through cell division, it has to overcome this checkpoint.
Do you mean that you don't understand what the cell cycle does or do you mean you don't understand what the checkpoints do? The cell cycle is just the life cycle of cells that divide. It has three main parts: interphase, mitosis, and cytokinesis. It's so important because organisms need cell division for growth, development, repair, replacement of worn out cells, and so on.
Why do many molecules not break down rapidly into smaller molecules, even when it is energetically favorable? Breaking down rapidly would release too much energy at once in an uncontrolled fashion. This would damage the cell instead of helping it. Just think of the way your car burns gasoline - a little puff of gasoline at a time is burned. You could get a lot more energy out of the gasoline quickly by throwing a match into the gas tank, but that isn't a good idea. Same thing for controlled, regulated energy release within cells.
Competitve inhibitors bind to the enzyme in the same place that the substrate would normally bind. The inhibitors "compete" for the binding site with the substrate.
Cellular respiration is far more efficient than fermentation. Respiration yields 38-40 ATP per molecule of glucose. Fermentation yields only the 2 ATP that were gained during glycolysis.
That's all I've got!!! | | | |
| Q. | Is Jay Mohr (Professor Payne) ever coming back to Ghost Whisperer? | Related Search: Other - Television | | |
Well, he did tell the producer not to kill him off, just in case Gary Unmarried goes badly. But I hate Jamie and I want Jay back :(
| | A. | I believe he said if his show is not carried into a new season, or his season gets hacked halfway through like many shows do, he will return to Ghost Whisperer. | | | |
| Q. | What do you do when your professor insists you call them by their first name? | Related Search: Higher Education (University ) | | | He insists we call him Jay not Dr._______ or Professor _______, and everyone does, but I feel really weird calling him Jay because I want to ask him for a recommendation letter and it seems like I would come across as unprofessional . Do teachers who insist on their students calling them by their first names really mean it, or do they expect students to call them Prof____ or Dr_____?
| | A. | Call him what he wants to be called. How would you feel if someone called you something you specifically requested they didn't? It's possible he's not a dr. or a full professor. He's more likely to give you a better rec if you do as he asks you to. | | | |
| Q. | How do some people who call themselves Christians, deny the very Bible that Christianity is based on? | Related Search: Religion & Spirituality | | | In his classic 1923 book, Christianity and Liberalism, the great Presbyterian scholar and Princeton Professor Jay Gresham Machen reminds us that people who deny the fundamentals of the Christian faith are not just liberal Christians; they belong to another religion entirely. When it comes to liberalism, Machen wrote, Christianity "is battling against a totally diverse type of religious belief," rooted in naturalism. Despite its use of Christian terminology, "liberalism not only is a different religion from Christianity but belongs in a totally different class of religions."
