Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain protei

ns that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?

Nasim is driving on a snow-covered road, and her car begins to slide. The quick behavioral response and the increased heart rate
Luda [366]

Answer:

1. sympathetic

2. parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.  

Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.

Aleksandr-060686 [28]

Answer:

The cross is as follows:

P: D/d × d/d

Explanation:

Half of the F1 progeny are mutant. The mutation results in 3 cotyledons is dominant and the original mutant is heterozygous.

If D denotes the mutant allele and d denotes the wild type allele.

The cross is as follows:

P: D/d × d/d

F1 denotes D/d three cotyledons

d/d denote two cotyledons
