Glycolysis only: heokinase & pyruvate kinase
Glycolysis and gluconeogenesis: triosephosphate isomerase
Gluconeogenesis only: pyruvate carboxylase & glucose 6-phosphate
In contrast to gluconeogenesis, which is crucial for sustaining blood glucose levels during hunger, glycolysis is a catabolic process of glucose hydrolysis required for energy and biosynthetic intermediates.
When blood sugar levels fall, the liver breaks down glycogen, whereas the liver and kidneys produce glucose from non-carbohydrate sources like lactic acid, glycerol, and amino acids.
Two pyruvate molecules are created during glycolysis, the initial stage of the breakdown of glucose.
Both prokaryotic and eukaryotic cells undergo glycolysis in the cytoplasm.
Gluconeogenesis is the opposite of glycolysis, where two pyruvate molecules combine to generate a glucose molecule.
Aldolases A and C are primarily involved in glycolysis, while aldolase B is involved in both glycolysis and gluconeogenesis. The various isozymes have various catalytic roles.

Aerobic and anaerobic respiration are process through which organism obtain energy from the
food they eat. Describe the processes of aerobic and anaerobic respiration. Identify an
example of each.
Answer:
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy while Anaerobic respiration is respiration using electron acceptors other than molecular oxygen.
Explanation:
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP)
An example is respiration in humans.
Anaerobic respiration: In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is a high-energy [2] oxidizing agent and, therefore, is an excellent electron acceptor. In anaerobes, other less-oxidizing substances such as nitrate (NO3−), fumarate, sulphate (SO42−), or sulphur (S) are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Therefore, anaerobic respiration is less efficient than aerobic.
Example: In anaerobic respiration, the process occurs in the absence of oxygen such as alcohol fermentation, lactic acid fermentation (which can result in yogurt and in sore muscles), and in decomposition of organic matter.

Natural selection does not
a. Produce the mutations
b. Select those mutations that give an organism an advantage
Natural selection does not produce the mutations that are in option A, as natural selection is the process by which certain advantageous traits become more common in a population over time because individuals with those traits are more likely to survive and reproduce.
Natural selection does not produce the mutations themselves. Mutations are random changes that occur in an organism's DNA and can happen for various reasons, such as exposure to radiation or mistakes during DNA replication. Natural selection acts on the variation already present in a population, selecting for traits that confer advantages in a given environment and allowing those traits to become more prevalent over time.

Which of the following best describes how does latitude affect biomes?
Latitudes affect how much rainfall a biome will receive.
Lower latitude biomes will always have high temperature.
Higher latitudes produce warm biomes.
Higher latitudes receive less sunlight producing cold biomes.
Answer:
Higher latitudes receive less sunlight producing cold biomes.
Explanation:
Regions with similar climates and plant types are called biomes.
Terrestrial regions may be classified as desert biomes, rainforest biomes, grassland biomes, temperature deciduous forest biomes, tundra biomes, northern coniferous forest biomes, savanna biomes, and mediterranean biomes.
Because these biomes are mostly defined in terms of dominant vegetation or plant species, they are determined by rainfall and temperature. In general, higher latitude biomes are further away from the equator, less sunlight and heat- this results in drier climates with less rainfall and lower, cooler, temperatures.
Summarize the structures blood has to flow through from the vena cavas until it leaves out the pulmonary arteries
The blood (without oxygen) enters the right atrium of the heart through the inferior and superior vena cavas. From the right atrium, it flows to the right ventricle through the tricuspid valve. Then, the right ventricule squeezes when it's full, closing the tricuspid valve and opening the pulmonary valve. The blood then flows through the pulmonary arteries, entering the lungs, where it gets oxygen. The blood will then leave the lungs through the pulmonary veins, entering the left atrium. From the left atrium it flows through the mitral valve, going to the left ventricle. It leaves the left ventricle and leaves the heart through the aortic valve, flowing in the aorta to reach the rest of the body.
Describe the role of GA in a-amylase production and in germination. Provide evidence for your claim
Gibberellic acid (GA) plays a crucial role in a-amylase production and germination. GA stimulates the synthesis and release of a-amylase enzymes, which hydrolyze starch into sugars during germination. Experimental studies have demonstrated that the application of GA accelerates a-amylase production and enhances germination in various plant species
In terms of a-amylase production, GA stimulates the synthesis and release of this enzyme. a-amylase is responsible for breaking down starch into simpler sugars, which are then utilized by the plant for growth and development.
Studies have shown that applying GA to plant tissues or seeds results in an increased production of a-amylase, facilitating the conversion of stored starch into energy-rich sugars.
Regarding germination, GA is involved in breaking seed dormancy and promoting the growth of the embryonic plant.
It stimulates the production of hydrolytic enzymes like a-amylase, which enable the hydrolysis of starch reserves in the endosperm, providing the energy needed for germination and seedling establishment.
Additionally, GA helps in cell elongation and division, promoting the growth of the embryo and the emergence of the radicle.
Evidence for GA's role in both processes includes studies where the exogenous application of GA to seeds or plant tissues has been shown to enhance a-amylase production and promote germination.
Conversely, inhibiting GA synthesis or action results in reduced a-amylase activity and impaired germination. These findings support the critical involvement of GA in both a-amylase production and germination processes in plants.

What is one effect of Earth's rotation?
One effect of Earth's rotation is the creation of the Coriolis effect, which causes moving objects (such as wind, ocean currents, and the trajectories of projectiles) to be deflected to one side as they travel along the planet's surface. This results in the formation of rotating weather systems and ocean currents, as well as the characteristic eastward flow of the jet stream. The Coriolis effect is stronger at the poles and weaker at the equator, and it affects the direction of movement of many large-scale natural systems on Earth.

Answer:
A
Explanation:
Different kinds of substances have different properties. Compare and contrast the electrical properties of salts, metals, and acids.
Salts, metals, and acids are three different types of substances exhibiting unique electrical properties.
Thus, salts are ionic compounds and exhibit electrical properties as they have both positively charged ions and negatively charged ions. They can dissociate in solution into their constituent ions to conduct electricity, but they can not conduct electricity in the solid state.
Like salts, metals also conduct electricity due to their free-moving electrons. They have high electrical conductivity and are used in electrical wiring and other applications. Acids release hydrogen ions when dissolved in water which allows them to conduct electricity because the hydrogen ions move freely and carry an electrical charge when acids are dissolved in water, thereby, exhibiting electrical properties.
