Mary asks…
Where do the calories come from in metamucil?
all the carbohydrates listed are soluble fiber and dietary fiber…
5 carbohydrates = 20 calories, but since fiber cant be used as energy…. are the calories coming from an unlisted amount of protein?
I know the ingredients include maltodextrin which is a complex carbohydrate….
Is this where the calories are coming from the complex carbohydrates that they dont list?? Or would that be included in the total carbohydrates?
The package lists it like this..
total carbohydrates = 5 grams
Dietary fiber = 3 grams
soluble fiber =2 grams
just a little confused on how this will affect on my low carb diet…
admin answers:
Yes the calories come from the fiber, maltodextrin is a carbohydrate that does aid in energy, but since its a complex carbohydrate it does not effect blood insulin levels. One gram of carbohydrates has 4 calories, no matter what the source. There for, 5 carbs times 4 cals a carb= 20 cals.

1. What is RNA and explain what it does and aslo do the same wth DNA pelase and thank u .?
RNA is just single stranded. DNA is double stranded.
Just remember this: DNA is your genetic information, and it is the exact sequence to make protein. However, since it is so important data, that it need some “copy machine” to do the work.
So Before protein can be made, it needs to be transcipt to RNA, then translate to protein. You may want to check out central dogma. RNA have a few types. MRNA, tRNA, rRNA, etc. They are all required to make protein during the central dogma steps.
2. What are the six characteristics of living things?
They contain DNA or RNA(for virus only, but not consider as living thing) , Cell, organelles. They breathe, they eat, they metabolize and reproduces.
3. Diffence betweet simple adn complex carbohydrates?
What is adn?
4. Example of food source tht contains simple carbohydrates?
Glucose water?
5 Example of a food sourcethat contains complex carbohydrates?
Bread? Rice? Sweet potato? They need enzymes to change them into simple carbohydrates,
6. List the 5 building blocks of cell and describe one function of each……
Plant or animal cell?
DNA: genetic information for the organism to make protein
Cell membrane: protect the cell
Cytoskeleton: give the shape of the cell
mitochiondrion: Contain enzymes that break down ATP to ADP.
Cytoplasm: contain floating enzymes and chemical that helps make cell pH level and oxygen level, and water level.
7. Explain why an organism that lives in land has more complex mechanism to maintain homeostasis than one living in water.
If not, without homeostatsis mechanism, you tend to fall sick /die much easily because different temperature, pH, water level could kill you. Compared to organsim on water, temperature is more constant.
8. Explain why a single- celled organsim produces an offspring identical to itself . THEN summeriza the section phspholipids…
????? WHAT THE HELL? I see no link in this question.
Jenny asks…
Give at least 5 examples of enzymes and identify each enzyme’s substrate and reaction products?
An important step in utilizing complex carbohydrates as an energy source is to break their glycosidic linkage. This is necessary because the digestive system cannot absorb any carbohydrates larger than a monosaccharide. Compile a list of at least 5 enzymes that can accomplish this. Identify each enzyme’s substrate and reaction products. You may include enzymes found in any organisms…
HELP!!!

Http://en.wikipedia.org/wiki/Glycoside_hydrolase
Glycoside hydrolases are typically named after the substrate that they act upon. Thus glucosidases catalyze the hydrolysis of glucosides and xylanases catalyze the cleavage of the xylose based homopolymer xylan. Other examples include lactase, amylase, chitinase, sucrase, maltase, neuraminidase, invertase, hyaluronidase and lysozyme.
Bingo! 5 of these act in digestion.
Lactase, amylase, chitinase, sucrase, maltase (invertase too).
Lactase: the ?-glycosidic bond in D-lactose is hydrolyzed to form D-galactose and D-glucose.

Calories and carbohydrates and losing weight… Soo confused, please help.?
Okay so somebody PLEASE help me. I have tons of questions about tons of stuff so i didn’t know what to do for with question. Well people say not to eat carbohydrates when your on a diet. But can’t you still with excercise?!?! Gosh, ppl are dumb then!!! And if you can’t eat carbohydrates then they say complex carbohydrates, but wouldn’t it be either or because of excersice?!?!!! Can’t they be specific? I need to lose weight and im confused with all these “buts” & “ifs” annd “howevers” goddamned people. And then websites say(they are true not lies) that an apple a day keeps doctor away and it’s okay to eat more than one apple a day?? Well i just found out that apparently apples have carbs or complex carbs whatever…. But I thought apples were healthy?! Now can’t eat them cause’ they have carbs! So can I eat more than one apple a day? Does it matter how much excersice i get could i still have 2 or 3 for a snack? What about tangerines and bananas? Can i have more than one a day? And same thing applies, does it matter how much excersice i get?? OBVIOUSLY, im not gonna get the EXACT same amount of excersice i get each day, it’s gonna be varied right?? Like if I do 5 hours of excersice one day at my barn and then the other I day I don’t go to the barn and instead I walk home from school and do some house work which is 1 or 2 hours, can i still have the fruit??? I heard fruit is so healthy so shouldn’t u be able to eat a lot????? Like geez, it’s better than chocolate…. And on a site it states… “Complex carbohydrates are mostly found in vegetables, nuts, grains, oat meals, and nuts. Listed below are some of the examples of complex carbohydrates food:
Barley Oat bran bread Low fat yogurt Onions Zucchini Tomatoes Lentils Kidney beans Apples Grapefruits Pears Carrots Oranges, etc.,,
ughhh Im sorry I can’t finish the rest because there’s too much writing.

Hi,
Ok, right I am going to tell you something now. FORGET EVERYTHING YOU HAVE READ OR HEARD!!!! You are so confused you need to get back to basics ok.
Don’t worry about fruit being a carbohydrate, yes some have more sugar in than others, but it is better to eat an apple than tuck into cookies!
In UK we say high glycemic and low glycemic foods which I find more useful. So the higher the rating, the faster the sugar is absorbed into the blood stream.
So, go back to basics, think lots of veggies, lots of fruit, lean meat/fish whole grains, lots of water. Then allow yourself a tiny treat a day.
Hope this helps. More tips/advice? Just get back to me.
