The heterotropic effect is the effect of molecules other than substrate on allosteric enzymes.
What is the heterotropic effect?
The term "allosteric enzymes," which derives from the Greek "allo," which means "other," refers to enzymes that have a second site in addition to the active site. Enzymes can have many allosteric sites, which are these. They stand out because they can react to many circumstances in their immediate surroundings.Unrelated to the enzyme's substrate, a regulatory molecule is referred to as a heterotropic allosteric effector. The enzyme binds to can either be activated or inhibited by it.Carbon dioxide ([tex]CO 2[/tex]) is an excellent example of a heterotropic allosteric effector because it also functions as an effector of hemoglobin but is not an enzyme-substrate.To learn more about allosteric enzymes refer to: https://brainly.com/question/13150990

the growth of a plant in size is regulated by a plant hormone. explain
Abscisic acid
Abscisic acid serves as an antagonist to Gibberellic acid. It is also known as the stress hormone as it helps by increasing the plant-tolerance to various types of stress.
[tex]\underline{\color{yellow}{hope \: its \: help \: you}}[/tex]
Plant hormones, also known as phytohormones, regulate growth by influencing cell division, elongation, differentiation, and various physiological responses in plants. These hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene.
Plants regulate their growth in size through the action of plant hormones, also known as phytohormones. These are chemical messengers produced by various parts of the plant, such as the roots, stems, leaves, and flowers.
There are several types of plant hormones, each with specific roles in growth regulation:
Auxins: These hormones are responsible for cell elongation and differentiation. They promote growth by increasing the flexibility of cell walls, allowing cells to elongate. Auxins are also involved in tropisms, which are growth responses to external stimuli like light (phototropism) or gravity (gravitropism).
Cytokinins: Cytokinins promote cell division and growth in areas such as roots, shoots, and fruits. They play a role in controlling the balance between shoot and root growth.
Gibberellins: Gibberellins are involved in stem elongation, seed germination, and flowering. They stimulate cell division and elongation, leading to increased plant height and size.
Abscisic Acid (ABA): ABA is often called the "stress hormone" because it regulates responses to stress conditions like drought, cold, and salinity. during adverse conditions.
Ethylene: Ethylene is a gas that regulates fruit ripening, senescence (aging), and responses to mechanical stress. It plays a role in processes like leaf abscission (shedding) and root growth inhibition.
Thus, plant hormones, also called phytohormones, control growth in plants by affecting cell division, elongation, differentiation, and a variety of physiological responses.

Why have plants been implicated in the devonian glaciations and not in the proterozoic glaciations?
The reason why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is; Land plants had not yet evolved during the Proterozoic.
Why have plants been dying?The Devonian glaciation occurred in south America and caused a global narrowing of the warm climatic belts, sharp regression, increased clastic sedimentation.
Meanwhile, the Proterozoic glaciation occurred near sea level in low palaeolatitudes. Thus, we can say that the reasons why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is because land plants had not yet evolved during the Proterozoic.

How does biodiversity affect ecosystem stability?
A. Not all ecosystems are effected in the same way
B. Biodiversity has no effect on stability
C. More biodiversity increases stability
D. More biodiversity decreases stability
The ecology is absolutely necessary for biodiversity. Ecosystem stability also rises as a result of increased biodiversity.
What do you mean by biodiversity?
The term "biodiversity" is used to describe the variety of species that can be found on earth. It can include things like plants, animals, bacteria, fungi, and microbes. The diversity of life on earth is immense; while many species are still waiting to be discovered, many more have already gone extinct. The ecosystem is composed of every single living thing. It also covers their surrounding environment and how people interact with them.
The ecosystem depends heavily on the various species. Therefore, the ecosystem's ideal balance is impacted when a single species goes extinct or is lost. Plants use the energy from the sun as part of the ecosystem's cycle.

Q3. Why do we need to break big molecules into smaller molecules?
Answer:
In order for them to be quickly and easily absorbed.
________________________________________________
Short Answer:
Enzymes help break down large molecules for us since certain of their components are the only ones that are useful to us. In order to create proteins, lipids, and other components necessary for survival, the tiny molecules become soluble and are quickly taken into the circulation. Additionally, they could need to travel through some membranes, therefore when they are little, they can do so without difficulty.
________________________________________________
Long Answer:
The nutrients in food must pass the gut lining in order to exit the digestive system and enter our blood. This absorption occurs in the ileum and jejunum regions of the gut. In some regions, the gut lining is brimming with chemical systems that may latch onto the food's smaller molecules and "chaparone" them across the gut and into the liver. These "chaparone" molecules can hold small peptides and amino acids but not whole proteins. Greater floor fragments do not absorb. Without "chaparones," some of the stomach-digested products pass through the gut's pores, but they must be smaller than the pores. Only tiny pieces and certain fragments with complementary "chaparones" of the food we eat are molecular fragments that are absorbed. A number of gastrointestinal conditions are caused by an imbalance in the gut's capacity to absorb nutrients. One condition where iron is not effectively absorbed is Cooly's anemia. Iron deficiency affects Cooly's anemia patients, even if their stomachs digest food correctly and they have normal iron absorption. Catabolism is the process of dissolving big molecules into smaller ones. Catabolism releases energy by rupturing bonds. Anabolism creates new connections and needs energy to function. Catabolic reactions (destructive or biosynthetic process) breaks down large molecules and release energy

The major pathway of communication between the right and left hemispheres is the.
Answer:
corpus callosum.
..............
Answer:
Corpus callosum
Explanation:
Actually, the left and right brain hemispheres may communicate with one another because to a thick bundle of nerves called the corpus callosum (Latin for "difficult body"). The corpus callosum, which is divided into several sub regions, connects various sections of the hemispheres. The corpus callosum is subdivided into the rostrum, genu, body, and splenium from anterior (front) to posterior (back). The brain's left and right frontal lobes are linked by the rostrum and genu. The hemispheres of the temporal and occipital lobes are connected by the body and spleen.
With over 200 million axons, the corpus callosum is the brain's biggest fiber bundle. It is made up of tracts of white matter fibers called commissural fibers. It has a role in several bodily processes, including the communication between the:
Cerebral hemispheres.Motion of the eye and vision.keeping the right balance of arousal and focus.The localization of touch.The different parts of our visual field, which independently process pictures in each hemisphere, are combined by the corpus callosum, which plays a crucial role in vision. By connecting the language centers of the brain with the visual cortex, it also enables us to recognize the objects we view. In order for humans to find touch, the corpus callosum also transmits tactile information—which is processed in the parietal lobes—between the two hemispheres of the brain.
