The body performs many processes that depend upon energy and could not occur without a supply of atp. How does the energy from atp power the cellular reactions?.
ATP is an energy packed molecule which releases a molecule of phosphate upon hydrolysis. This is supplied to the cells undergoing metabolic reactions.
What is an ATP?ATP is adenosine triphosphate, a nucleotide molecule consisting of a sugar moiety called ribose, adenine as nitrogenous base and three molecules of phosphates attached to the sugar back-bone.
The phosphate group traps the energy. This energy is released when the phosphate bond is broken with the addition of water molecules. The ADP so formed is taken up by the cells as a source of energy for various biochemical reactions.

The organelle responsible for the biosynthesis of proteins that are destined for secretion by the cell is the.
Answer:
the ER
Explanation:
The organelle responsible for the biosynthesis of proteins that are destined for secretion by the cell is the Endoplasmic reticulum.
Thus, The endoplasmic reticulum (ER) is the organelle in charge of the production of proteins that are intended for cell secretion. The smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER) are the two areas of the ER that are involved in protein production and secretion.
Under a microscope, the RER appears "rough" because it is covered in ribosomes. These ribosomes create proteins that are either intended for secretion or insertion into the ER membrane.
As the proteins are being created, they move into the ER lumen, where they go through a number of changes, including folding, glycosylation (the addition of sugar molecules), and disulfide bond formation.
Thus, The organelle responsible for the biosynthesis of proteins that are destined for secretion by the cell is the Endoplasmic reticulum.

predict the temperature of the atmosphere at a height of 135km above the surface and 140km above the surface. explain your predictions
Temperature Increases.
For every 100 meters as we move above the surface of the earth , temperature decreases by 1 degree celsius. Because there is less air above you as you rise in elevation, the pressure drops. Air molecules spread out more when the pressure drops, causing the air to expand, and the temperature to drop.
But, near 135- 140 Km lies the thermosphere region.
Thermosphere- Between 80 and 400 km above the Mesosphere, this layer can be found. This layer reflects radio waves that are emitted from the earth. In this location, the temperature starts to rise once more as the altitude rises.
The gases of the thermosphere get denser even if they are still very thin. As a result, the molecules in this layer start to absorb incoming high intensity ultraviolet and x-ray light from the sun, which leads to a significant temperature increase.
Also the formula to calculate temperature-
For 135 km -
T = -131 + (0.003 * altitude in meters)
T = -131 + (0.003 x 135000)
T = -131 + (405)
T = 274 ° C
For 140 km-
T = -131 + (0.003 x 140000)
T = -131 + (420)

Do the usage of synthetic hormones for the modification of plant growth have any environmental implications?
Answer:
Yes, the usage of synthetic hormones for the modification of plant growth can have environmental implications.
1. One environmental implication is that it can lead to the development of herbicide-resistant weeds. If farmers are using synthetic hormones to make their crops grow faster, the weeds around the crops will also be exposed to the synthetic hormone and over time, they will develop a resistance to it.
2. Another environmental implication is that it can lead to soil contamination. If the synthetic hormone is not properly contained, it can leach into the soil and contaminate it. This can cause harm to other plants and animals that come in contact with the contaminated soil.
3. One final environmental implication is that it can disrupt the natural growth cycle of plants. By artificially manipulating the plant's hormones, farmers can make the plants mature faster. However, this can interfere with the plant's natural life cycle and cause problems in subsequent growing seasons.
What are synthetic hormones for plants?
Synthetic hormones for plants are chemicals that are added to the soil or sprayed on the plants to alter their growth.

If an amino acid does not contain an ionizable side chain, its net charge at physiological ph will be:________
The net charge (at physiological pH) on an amino acid which does not contain an ionizable side chain will be zero.
Amino acids contain both a carboxylic group (-COOH) as well as an amino group (-NH₂) . Both these functional groups are joined to a single carbon atom, i.e. α-carbon. Amino acids are the building blocks of proteins.
Both the functional groups present in an amino acid have the ability to form their respective ions in the solution. At physiological pH, i.e. pH = ~7.4, the amino group accepts a H⁺ ion and becomes protonated (-NH₃⁺) whereas, the carboxyl group loses H⁺ ion to form a negatively charged ion (-COO⁻ ).

When gtp hydrolysis takes place on a tubulin molecule at the plus end of a microtubule protofilament before another tubulin molecule is attached, the microtubule depolymerizes.
The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.
They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.
Microtubules are made up of just one type of globular protein called tubulin, as opposed to the diverse fibrous proteins that make up intermediate filaments. Tubulin is a dimer made up of the 55-kD polypeptides -tubulin and -tubulin, which are tightly connected to one another. Both - and -tubulin are encoded by small groups of linked genes, similar to actin.

Many people were catching a communicable disease called "Ugo". Most of these people were very sick and took 7 to 9 days to recover. Investigations directed by Dr. Kleinenstein had revealed that Ugo was caused by a pathogenic bacteria, Ugot diarrhea.
Kleinenstein had recently read in the 'Journal of Biochemistry' that an antibiotic called "norunium" was observed to kill the Ugo bacteria
After receiving permission from the appropriate government agencies Kleinenstein was ready to conduct an experiment on human subjects.
Tablets were prepared containing the antibiotic norunium. A second batch of tablets containing none of this antibiotic were also prepared (tablets containing no medication are called 'placebos').
1. What is Kleinstein’s probable hypothesis? State as an “if.. then…” statement”
Answer:
If norunium can kill the Ugo bacteria, then norunium tablets when ingested should see to a reduction of Ugo bacteria in the body.
Explanation:
Kleinenstein is basing his experiment based on the results of another (group of) scientist(s) that found that norunium can eliminate the Ugo bacteria. Based on "reproducibility and replicability", Ugo should, with the same steps, come to the same result as the scientist(s) who found that "norunium" can kill the Ugo bacteria.
One thing to note, is that if Kleinenstein is to re-test the experiment, generally there would be a step to see the effects of the antibiotics on animals first, before moving to human subjects.
