Explanation:
Compare substrates and inhibitors.
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. ... Not all molecules that bind to enzymes are inhibitors; enzyme activators bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.
Arginine utilizing enzymes in macrophages showed different specificities for various arginine analogues and derivatives as substrates and inhibitors. Isolated arginase was strongly inhibited by L-canavanine(Can) and L-ornithine(Orn) but only slightly by L-homoarginine(Hom) and L-argininamide(ArgNH2). These effects were not or only weakly observed when released urea was measured in long term cell cultures. On the other hand, both L-canavanine and L-argininamide were substrates for arginase in long-term cultures. The known inhibitors of NO synthase were ineffective. The mechanisms of inhibition were different for L-canavanine and L-ornithine, but clear mechanisms could not be identified). NO synthase was studied only in long term cell cultures without purification. Certain N-guanidino (NG)-substituted arginine derivatives caused a marked inhibition while inhibitors of arginase had only slight or no effect. L-homoarginine was also found to be the substrate of NO synthase. The comparison of these effects of arginine analogues and derivatives made possible a computer-aided approximation for the fitting of active centers of these enzymes to their substrates.
Secondary succession can happen after primary succession or independently of primary succession.

Answer:
it is true
Explanation:
i took the quiz
False. Secondary succession does not happen after primary succession or independently of primary succession.
What is secondary succession?Secondary succession is the process of ecological succession that occurs after a disturbance has disrupted an existing ecosystem, but left some soil and seed sources intact. Unlike primary succession, which starts with bare rock or soil with no living organisms, secondary succession begins in areas where there was already an established community of plants and animals.
Examples of disturbances that can lead to secondary succession include forest fires, landslides, and farming practices that disturb the soil. The process of secondary succession involves the gradual recolonization of the area by plants and animals, with different species replacing one another as the ecosystem gradually returns to a stable state.

What information cannot be studied effectively using human torso models? I. the approximate sizes of organs II. the textures of organs III. the interrelationships of organ functions IV. the positions of organs within the body
Answer:
II. the textures of organs
Explanation:
A human torso model is designed to be as accurate as possible so that students/researchers can understand the inner workings of the body. Therefore, the organs have been designed to be the same size of an actual human being of that stature, while also being in the correct position within the body to better understand the interrelationships between the organs. The only thing that is not accurate in these models is the texture of the organs as most are smooth plastic unlike the actual organs.

Interdependence of animals in the rainforest. Help me plss
Answer:
The Halloween Crab
Explanation:
Interdependence is the idea that all species depend on one another in some way. This connection is very important to the health of the rainforest because every species in the rainforest relies on at least one other to survive.
The Halloween Crab can only be found in the rainforests of Central America. The crab lives in borrows it makes in the ground. By carrying leaves into their burrows, the crabs help the soil get the nutrients it needs. Them eating seeds off the ground ensures new plants will be able to grow. Finally, once they die their borrows will be used by other arthropods such as insects, spiders and other crabs.

1. Describe how photosynthesis and chemosynthesis differ in terms of how energy is converted,
Answer:
1) Photosynthesis:
Reactants- 6CO2 (carbon source), 6H2O, light energy
Products- C6H12O6 (organic molecule), 6O2
2) Chemosynthesis:
Reactants- 6CO2 (inorganic carbon source), 6H2O, 3H2S ( chemical energy source)
Products- C6H12O6 (organic molecule), 3H2SO4
Please find the difference in terms of how chemosynthesis and photosynthesis convert energy below
Explanation:
Photosynthesis and Chemosynthesis are both autotrophic forms of nutrition. They differ in the form of energy and reactants' used to power their respective processes.
- Photosynthesis is the process whereby plants synthesize their food (glucose) from carbon dioxide (CO2) and water (H20) in the presence of sunlight as energy, releasing oxygen gas (O2) as a product.
6CO2 + 6H2O -> C6H12O6 + 6O2
- Chemosynthesis, on the other hand, is the process whereby certain bacteria and fungi that lacks access to light synthesize organic food (glucose) from an inorganic carbon soure (carbon dioxide, CO2), water (H2O), and hydrogen sulfide (H2S), used as chemical energy source, releasing sulfates (H2SO4) as a product
6CO2 + 6H2O + 3H2S -> C6H12O6 + 3H2SO4
However, photosynthesis converts solar energy (energy in sunlight) to chemical energy (in glucose) while chemosynthesis converts inorganic chemical energy to organic chemical energy.
The chemical reaction(reactant and product) for photosynthesis and chemosynthesis are as follows:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S
Photosynthesis reaction:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂This reaction is a reaction between carbon dioxide and water to form sugar and Oxygen in the presence of sunlight.
The chemical equation of photosynthesis can be interpreted as 6 molecules of carbon dioxide reacting with 6 molecules of water to form a simple sugar and 6 oxygen molecules in the presence of sunlight . The names of the reactant and products are as follows:
carbon dioxide + water → Sugar + oxygen
Chemosynthesis reaction:
Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.
Using H₂S as an energy source a chemosynthetic reaction can be represented below:
18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18SFrom the reaction Hydrogen sulphide was used as a source of energy and it reacts with carbon dioxide and oxygen to produce sugar, water and sulphur.
Hydrogen sulphide + carbondioxide + oxygen → Sugar + water + sulphur.
