PEP + ADP → Pyruvate + ATP ∆G = -14.8 kcal/mol
ATP + H2O → ADP + Pi ∆G = -7.3 kcal/mol
Glutamic acid + NH3 → Glutamine ∆G = +3.4 kcal/mol
Which reactions can be coupled?
Reactions can be coupled if the products of one reaction are reactants in the other reaction, and if the overall ∆G of the coupled reactions is negative. Therefore, reaction 3 (Glutamic acid + NH3 → Glutamine) is the non-spontaneous reaction among the given reactions.
We can see that in this instance, the first two processes involve the interconversion of ADP and ATP and have negative G values. As a result, they are both exergonic, or processes that release energy.
These two reactions can therefore be coupled because the first reaction's energy discharge can be used to fuel the second reaction.
The third process, on the other hand, produces glutamine from glutamic acid and ammonia and has a positive G value. This indicates that it is an endergonic process, which uses up energy.
This reaction therefore cannot be coupled immediately to either of the first two reactions. Therefore the reaction 3 is correct.

Laetiporus sulphureus, or chicken of the woods, is a multicellular organism in the Fungi kingdom. It obtains its nutrition as a heterotroph by decomposing dead wood. It is known for its bright color and spongy texture when cooked.
Laetiporus sulphureus, also known as chicken of the woods, is a multicellular organism that belongs to the kingdom Fungi. It is a heterotroph, meaning it obtains its nutrition by consuming organic matter. Chicken of the woods is a saprophytic fungus, which means it decomposes dead wood and obtains nutrients from it. It is commonly found growing on the trunks of trees, particularly oak and cherry trees.Chicken of the woods is characterized by its vibrant orange or yellow color and its bracket-shaped fruiting bodies. These fruiting bodies consist of layers of spore-producing tubes underneath. The mushroom has a soft and spongy texture when cooked, making it a popular ingredient in various culinary dishes.For more questions on Laetiporus sulphureus

Is enzyme activity a form of cell regulation
An investigation involving osmosis and plant cells was performed by a group of students. Sweet potatoes were used as
the source of plant cells in the experiment. A sweet potato was diced into evenly sized andshaped cubes and placed
in beakers containing various glucose concentrations. The experimental setup is shown in the table here.
Which statements accurately predict the beaker in which water will enter the cells at a greater rate, causing an
Increase in mass for the sweet potato cells?
A)
Beaker 1
B)
Beaker 3
C) beaker 4
Answer:
A
Explanation:
Water will enter and leave the cells at the same rate via osmosis
The correct option is (A) Beaker 1 in which water will enter the cells at a greater rate, causing an increase in mass for the sweet potato cells.
What is Osmosis?Osmosis refers to a process in which the water or solvent diffuse across a semipermeable membrane (here cell membrane) from the area of high solute (here glucose) concentration to low solute concentration. The concentration of glucose in the water of beaker 1 is 1.5M which is highest as compared to other beakers.
The concentration of glucose solution in beaker 1 is hypertonic to the concentration of glucose in the cell which makes the water to move inside the cell via osmosis. Movement of water inside the cell results in increase in mass for the (sweet potato) cells.
Thus, the water will enter the cells at a greater rate in the beaker 1 because the glucose concentration is highest in the beaker 1 corresponding to its cell glucose concentration.

Explain how different links can show a relation between two species. Describe evidence that shows other correlations and causations between the species.
Different links show relationships between two species. In the scientific world, there are three types of links, including mutualism, parasitism, and commensalism.
Mutualism is a relationship in which both species benefit. Parasitism is where one species benefits, and the other is harmed. Commensalism is a relationship in which one species benefits, and the other is not harmed or helped.One example of a mutualistic relationship is the bee and flower relationship. Bees collect nectar and pollen from flowers for their food, while at the same time, the bee helps in pollination. The bee gets food from the flower, and the flower is pollinated. This is a mutualistic relationship. A parasitic relationship is the relationship between tapeworms and humans. Tapeworms live inside the host and get their food from the host, thereby, causing harm to the host. Evidence that shows correlation and causation between the species includes physical changes in the organism or adaptations to the environment. For example, an animal that feeds on a certain plant may evolve to have a longer tongue to reach the nectar of that plant. In summary, different links show relationships between species, including mutualism, parasitism, and commensalism. The evidence for the correlation and causation between species includes physical changes or adaptations in the organism or environment.For more questions on species

why are summer days longer than winter days on earth ?
Answer:
3. The region of Earth => away from the sun.
Explanation:
In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. This means we get more sunlight, making the days longer.

Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria
The reason for the clear zone may be that there is Insufficient lipolytic activity.
Why the clear zone?The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.
Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media. There wouldn't be any observable clearing or lipid hydrolysis zones as a result.
