Why growth hormone increases blood glucose?
by decrease glucose uptake by the cells and by gluconeogensis
Why does the root need root hairs for the uptake of water and mineral?
because absorption of water takes place by root hairs in the root
Why does the root need root hairs for the uptake of water and minerals?
Because it increases the surface area of which the roots can absorb water allowing it to absorb more water than it can with root hairs.
Why respiration rates may increase in root hair cell during the uptake of minerals ions?
Respiration rates may increase in root hair cells during the uptake of mineral ions because the minerals are taken up into the plant against the concentration gradient. This requires energy to use active transport, which then increases the rate of respiration.
What is the effect of size of uptake on diffusion in agar?
larger the size, the smaller the surface area to volume ratio, hence the slower the rate of diffusion into the agar jelly :)
What trace mineral is involved in the regulation of glucose uptake?
Potassium is the mineral involved in the regulation of glucose uptake.
Benefit of large water uptake in plants?
A Large Mineral Uptake
WHAT Vitamin increases THE amount of iron IN THE BLOOD?
Vitamin C increases iron uptake.
Do roots take in the water needed by the plants and also mineral salts?
Yes roots roots do both,root hairs absorb minerals dissolved in water .Water uptake from the soil by root cells is passive, and also follows osmotic gradients caused by the mineral nutrients
What hormone increases glucose uptake into muscle and adipose tissue?
Insulin
How does recovering oxygen uptake restores metabolic conditions?
increases levels of lactic acid
Why growth hormone increases blood glucose?
by decrease glucose uptake by the cells and by gluconeogensis
Why respiration rates increase in root hair cells during the uptake of mineral ions?
due to active transport system
How does the presence of hair cells of roots enables effecient absorption of water?
They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.
Why thyroxin is called as calorigenic hormone?
Thyroxin is a calorigenic hormone because it increases oxygen uptake and metabolism by the tissues and thus accelerates energy production,i.e., increases BMR
Does not describe how recovery oxygen uptake oxygen deficit restores metabolic conditions?
increases the level of lactic acid in the muscle
Why does the root need root hairs for the uptake of water and mineral?
because absorption of water takes place by root hairs in the root
