Answer:
D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.
Explanation:
Glucose is a polar, large, and hydrophilic molecule that cannot easily diffuse the cell membrane. It moves across the membrane through a mechanism known as <u>facilitated diffusion</u>. In this process, a carrier protein attaches itself to glucose molecule and transport it without any use of ATP. Instead, the movement is driven by concentration gradient. An example is the diffusion of glucose in red blood cells.
Heart rate. <span>From this site, the two channels of the autonomic nervous system originate the sympathetic and parasympathetic components. The sympathetic components increase heart rate by releasing the neural hormone catecholamines - epinephrine and norepinephrine. These hormones are cardio accelerators. Acceleration of the heart rate is called tachycardia.</span>
Answer:
The conversion of ADP to ATP using light energy
Explanation:
Photophosphorylation is a stage in photosynthesis in which ADP is converted to ATP using sunlight energy.
Note that, in photophosphorylation, 2 ATPs are produced
This process is fundamental in maintaining a stable energy level in our eco-system.
The two new strands are different from each other ,both of them have only one strand from the original DNA and the other strand is complementary . eg if a strand has the following base pairs .. AACCGGT ( consider this as the strands)
TTGGCCA
now they are going to be seperated AACCGGT TTGGCCA
TTGGCCT AACCGGT
as u can see the two NEW strands formed are similar but NOT IDENTICAL to each other .
This skin is known as the body membrane
