Why do humans need carbahydrates?
Your brain requires an uninterupted flow of oxygen and blood glucose to function. The brain needs large amounts of the sugar, glucose, which is its primary energy source. The mature, healthy, mammalian brain uses only glucose to obtain energy. A second function is the breakdown of glucose contributing to the formation of the neurotransmitters.
The carbohydrates we use as foods have their origin in the photosynthesis of plants. They take the form of sugars, starches, and cellulose. The best source of glucose is carbohydrates (another source is protein). If you do not eat carbohydrates you will, usually, not have enough glucose. If you do not have glucose your brain begins to starve. When your brain is starving you do not think clearly and everything becomes secondary to a sugar source to your glucose starved brain. Lack of glucose energy to the brain can cause symptoms ranging from headache, mild confusion, and abnormal behavior, to loss of consciousness, seizure, and coma. Severe hypoglycemia [low blood sugar (low glucose)] can cause death.
Not all carbohydrates are the same, some are simple sugars like monosaccharides or disaccharides while some are complex carbohydrates like starches or polysaccharides. A simple sugar like sucrose or table sugar is made up of glucose and fructose. It is disaccharide composed of two monosaccharides. Starches are polymers, long repeating chains, of glucose. Plants convert excess glucose into starch for storage. Starch is hundreds to thousands of glucose units long. This is why we eat things like wheat, corn or potatoes, they offer a large slowly digestible source of glucose that is a necessity to us.
"Glucose is the major substrate that sustains normal brain function. When the brain glucose concentration approaches zero, glucose transport across the blood-brain barrier becomes rate limiting for metabolism during, for example, increased metabolic activity and hypoglycemia."
"Although insulin is not supposed to play a role in the brain, recent evidence in both lab animals and humans suggests that the hormone may be needed for normal brain functions, including learning and memory; if so, defects in the brain's ability to use insulin could lead to anything from mild memory loss to Alzheimer's disease. The idea is still controversial, however, partly because no one yet knows exactly how insulin might affect brain neurons. Some researchers suggest that the hormone chaperones glucose to brain neurons and thereby helps them maintain their energy production, in which case, memory loss might result when brain cells lack insulin and become glucose starved. Others hypothesize that insulin has other beneficial roles, such as spurring neuronal growth and inhibiting the formation of brain lesions called neurofibrillary tangles that characterize Alzheimer's. If insulin's role in cognition can be pinned down, though, the work might one day point the way to drugs that could reduce memory loss in both Alzheimer's and normal aging."
Carbohydrates are basically used for quick energy
They're your body's primary energy source.
they dont replace put take the carbahydrates into blood stream. :) :D
Humans need to eat plant food. Plants need carbon dioxide which humans exhale.
Humans need and good job that makes good money. Humans also need food and a good but affordable car. They also need health insurance.
yes that is true animals do need humans to survive
humans need proteins to make good muscles and health.
Humans need exercise to be heatlth and fit also because our musles need to gain strenth
Oxygen is the gas humans and animals need to breathe in.
do animals need more oxygen than humans
Just as humans need water to live and grow. We just need it. Just as humans need water to live and grow. We just need it.
What would humans need to bring with them or how would humans have to change to help them deal with the amount of oxygen mercury?
Humans need to bring food, water, oxygen,
Humans need a heart because the heart pumps their blood and blood makes you live.
humans need organs so that the body flow will go right and your food will dijest
Humans need water to survive because it provides hydration to the body and organs.
The one thing humans need in order to grow is water.
Humans need: WATER OXYGEN A SPACE SUITE to lsurvive on Saturn
As humans we need to learn to balance the need for resources with the need for conservation. This can be done by making informed, educated choices and not being selfish or greedy.
They basically do what humans do to survive. Like humans need to eat to survive and we also need to sleep to survive.
Humans. Ligers are not found in the wild, so they need the care of humans to allow them to survive and live.
yes they do, humans need all sorts of protien ect.
Humans need oxygen to undergo aerobic respiration.
We humans do not run on electricity, we run on food.
because humans have no need for it and we would probably be then rooted into the ground
because it has humans in it and humans need light
Opera is an art form. Operas tell stories. Humans need stories like humans need air.
humans need to smoke because they are most probably addicted and they do not worry about any side effect on them
Everything costs money, so humans need to earn a living to afford these things.
Humans really do not need a lot of things to invent a tool. All a human needs are there minds.
Squirrels need oxygen, just as humans do, so they breathe in air much the same way as humans do. Squirrel blood cells need oxygen to operate their muscels, bones, and anything else in their body, much the same need for oxygen in humans.
All humans need: food, water, oxygen, shelter,clothing and love.
Humans need shelter to protect them from the outdoors weather and climate you never know what mother nature has in store for us
humans are idiots to want to move to mars
kill people ,homes ,and things humans need
Humans need oxygen wherever they are.
they're ballbags need such an occurance
What if a tiger said why is there a need to save the humans.
humans need soil to grow trees to get oxygen and where would we be without oxygen and soil helps plants grow and not all plants need soil air plants do not need soil.
Well the things that humans do need are water/food safety shelter that's all what we really need.
Humans need milk for the calcium that it provides. Some people are allergic to milk and all dairy products and get calcium from supplements.
Humans are continously causing deforestation which is automatically stopping the things we most need and will come to need from producing itself.
humans do need some fat in there body because if they didnt have any fat in there body they would be incredibly to thin
I suspect that humans have the lowest hearing. Humans no longer need acute hearing to listen out for danger - as an antelope would need to do.
it is healthy for humans to eat fat because they need it for insulation.
They don't. Plants were just fine before humans were ever around.
Humans need food to use for energy, without energy we die basically.
because they don't work as hard as humans do
Before we let sensitive information out, we need to know what species you are, and what you will do with this information about humans.
For photosynthesis, plants need carbon dioxide, which humans exhale. Plants release oxygen, which we breathe in. That is why humans and plants need each other.
