The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is?
sineoko [7]

Answer:

The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is <u>less</u>.

Explanation:

Both ATP and glucose are energy containing molecules. However, a molecule of glucose has about 90 times more energy than a molecule of ATP.

But, ATP is used by most cells as the quickest source of energy. This is because ATP can easily be broken down to generate energy and it transfers energy very effectively.

A molecule of ATP is made up of adenine and three phosphate groups. The bond between the second and third phosphate is broken down to generate energy.

the neurotransmitter found at synapse between a motor neuron and skeletal muscle fibers is glycine A) True B) False
Masja [62]

Answer: Option A) True

The statement is true

Impulses of motor neurons could inhibit the cells of the effector (e.g skeletal muscles, gland). Hence, the axons cause the release of glycine which inhibits or checks muscular contractions.

Answer:

1) pathway taken by water

water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.

2) water potential gradient

water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.

Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.

3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.

Hope that answers the question, have a great day!
