Answer:
No
Explanation:
During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.
Answer:
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
Cellular respiration would produce less energy when plant were to lose much of its chlorophyll.
Plants can actually live longer without photosynthesis than they can without respiration. Some plants survive half the year without performing photosynthesis, but if they stop performing cellular respiration, even for a minute, they would be dead where they stand.
During photosynthesis, plants absorb sunlight and carbon dioxide from the air. Through a series of steps, much like cellular respiration, they convert these reactants into the products oxygen and glucose. The plants then can use the oxygen and glucose to make ATP in cellular respiration. The rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide is produced during respiration.

Answer:
A balance between Osteoblasts and osteoclasts maintain bone tissue.
Explanation:
Osteoblasts are bone making cells, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.
