Answer:
Only P-, F-, and V-class pumps transport ions.
Explanation:
The distinct classes of ATPases include:
1) Only the P-type ATPase actively transports ions across biological membranes. P-ATPases (also named E1-E2 ATPases) are found both in plasma and organelle membranes. These ATPases serve to transport ions and phospholipids by hydrolyzing ATP to ADP and phosphate.
2) A- and F-ATPases synthesize ATP by transforming the energy from a gradient of ions across the cell membrane.
3) V-ATPase (also known as Vacuolar-H+ ATPases) acidifies vacuole, lysosome, endosome and Golgi membranes. This type of ATPase couples the hydrolysis of ATP to the active transport of protons across biological membranes.
4) E-ATPases hydrolyze extracellular ATP.
Answer;
-Ability to catalyze biochemical reactions
Explanation;
-Carbohydrates and proteins are very important macromolecules that the body needs in significantly larger quantities together with lipids, as compared to other nutrients like vitamins or minerals, for a healthy life.
-Carbohydrates are organic compounds made up of carbon, hydrogen and oxygen and they are required by the human body as an energy source, while are organic compounds made up of interlinked chains of amino acids, which consist of carbon, hydrogen, oxygen, nitrogen, and sulfur.
Apart from the structure and element composition, carbohydrates and proteins differ in a number of ways, these includes; carbohydrates are the body’s main source of fuel that enables it to function, proteins are the building blocks of the body.
Carbohydrates are needed by the body to make it run and function, while we need proteins to keep our muscles and glands healthy. Additionally, proteins have the ability to catalyze biochemical reactions a major feature that differentiates it from carbohydrates and other macromolecules.
Answer:
stages of the nitrogen cycle
1. Nitrogen-fixation
Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.
Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.
2. Feeding
Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.
3. Production of nitrogenous waste products
Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.
4. Decomposition
Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.
5. Nitrification
A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.
6. Uptake of nitrates
Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.
7. Denitrification
This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.
Answer:
Energy is used up while running, and cellular respiration needs oxygen to produce more energy. Energy is used up while running, and cellular respiration needs carbon dioxide to produce more energy.
Explanation:
Answer and Explanation:
- Where (quadrant, etc.) will the doctor palpate Juan's abdomen?
<em>Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).</em>
- What other organs might be compressed by Juan's enlarged spleen?
<em>The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed. </em>
- why is Juan's spleen enlarged and not his stomach or kidney?
<em>The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.</em>
The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.
