<h3><u>Answer</u>;</h3>
- The amount increases as the object is lifted higher
- The amount varies according to the mass of the object
<h3><u>Explanation</u>;</h3>
- Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
- The equation for gravitational potential energy is mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
- <em><u>The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in</u></em>.
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
Answer:
The response would be approximately 38 ATP for each metabolic cycle.
Explanation:
It seems a bit sloppy to me the way the question is written, as for what I have mentioned, what I can answer is the following ...
Free oxygen radicals and high concentrations of peroxide, which is the union between water and free protons in the medium, generate an oxidation-reduction reaction in the tissues that destabilizes the positions of the electrons of the tissue ions (only those found in the latter orbit of the compounds), this results in a process called cellular oxidative stress that triggers aging.
As for the process of phosphorylation of glucose to use it as an energy reserve in the form of starch or glycogen, this phosphorylation is carried out by means of a chemical reaction that what it allows by means of enzymes is that at carbon number 6 of the glucose is added or a phosphorus is added, in this way the glucose is disabled for spontaneous consumption and is administered as an energy reserve of the organism.
Answer:
C.Never swims fast
Explanation:
RacerX and Speed protein need to bind to each other for the cilia to beat faster which would make the protozoan swim faster. However, Speed needs to be phosphorylated to be able to bind to RacerX. Thus, phosphorylation of Speed is necessary for the fast movement of cilia.
Threonine residue is phosphorylated in Speed protein. It occurs on its side chain through the formation of phosphoester bond. Apart from threonine, phosphorylation can take place on serine and tyrosine side chains again through the formation of phosphoester bond. It can also occur on histidine, lysine and arginine by formation of phosphoramidate bonds.
Since, alanine can not form any of these bonds it can not be phosphorylated. Hence when threonine is substituted with alanine in Speed protein, it can not be phosphorylated. Racer X wont be able to bind to Speed and cilia wont beat faster. As a result the protozoan will never swim fast.
