The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
Why rate of anaerobic respiration is faster in starch than in glucose?
Infact it should. It is a common misconception that because Glucose is a monosaccharide that it should provide a higher rate of respiration as it does not need to be broken down, unlike sucrose. However, the method the glucose enters the yeast enters the cell is by facillitated diffusion and this requires carrier proteins. When glucose is being absorbed, there will be a point where the rate reaches it's maximum, i.e. all the carrier proteins are being used. When sucrose is the substrate, it is split into glucose and fructose. When all the carrier proteins are used transporting glucose, different proteins are used for fructose (due to the tertiary structure of the protein) so the composite monosaccharides of sucrose can enter the yeast at a higher rate. Hence the rate is faster.
What does 'villi' have to do with respiration?
Glucose is absorbed from the food in our small intestine. Inside the small intestine we have small finger like structures called villi. The glucose is absorbed by the villi. The glucose is absorbed (moves through) the villi and enter our blood system. Glucose is transported by our blood to all the cells in our bodies. Respiration takes place in our cells (in the mitochondria of cells). Respiration is where glucose (our bodies fuel) combines with oxygen (we breath in) to give us ENERGY, carbon dioxide and water.
Components of plasma?
water, glucose, amino acids, salts, hormones, blood proteins and anti bodies
What is the principle source of energy for brain cells?
The human body primarily uses glucose, a type of simple sugar, for energy. We convert the energy stored in glucose into a molecule called ATP which is what powers most of our cellular activity.
What does the human bodies burn that produces Carbon Dioxide?
In general, glucose.
Why glucose is injected in human bodies to supply energy instead of sucrose?
because glucose is simpler than sucrose.
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
the receptors on the protein carrier recognise glucose allowing it to enter the cell :)
What Carrier Proteins Transport Glucose Into A Muscle Cell?
carrier proteins transport glucose into a muscle cell
What do our bodies use glucose for?
Glucose is the simple sugar that is the primary source of energy used by our bodies during metabolism.
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
What reactions will usually be irreversible regarding chemical equilibrium in human bodies?
A) glucose to co2 and h20 B) ADP+Pi to make H2CO3 C) H2O+ CO2 to make H2CO3 4) glucose molecules joined to make glycogen
Why is glucose important for and animal?
Glucose is processed in animals' bodies to create energy to survive.
Who invented human bodies?
Human bodies were not 'invented'.
How can a cell that consumes glucose speed up its intake of glucose from the environment?
If there are more carrier proteins, more glucose can enter the cell. This is because the glucose enters the cell through facilitated diffusion.
What mechanism by which glucose can enter the cytoplasm without expending ATP is?
a carrier protein
What is the name of the carrier type that moves two solutes such as glucose and sodium?
Symport
