What happens to glucose which enters nephron along with filtrate

Answers

Answer:

it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion.

When glucose enters nephron along with filtrate, it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion. Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. Glucose that enters the nephron along with the filtrate after passing through the glomerulus, passes from the tubule of nephron where it is selectively reabsorbed and sent back to blood.
The filtered part of blood that is collected into the Bowman's space is called glomerular filtrate . ... Once the filtrate passes through the proximal convoluted tubule , the primary site of absorption, 100% of the glucose is reabsorbed back into the blood, including other nutrients and molecules. Nephric filtrate goes to Bowman's capsule when glucose comes out from it. The filtrate then passes through the tube where the blood capillaries absorb glucose. The capillaries of the blood carry glucose to all the cells of the body. Reabsorption. Reabsorption takes place mainly in the proximal convoluted tubule of the nephron . Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules. Following a meal, glucose utilization by the kidney increases. Normally each day, ∼180 g of glucose is filtered by the kidneys; almost all of this is reabsorbed by means of sodium–glucose co-transporter 2 (SGLT2), expressed in the proximal tubules.

Photosynthesis produces chemical energy and Cellular Respiration uses chemical energy. What type of chemical energy do they both use?


A. protein

B. sunlight

C. food

D. glucose

Answers

Answer:

Photosynthesis uses energy from the sun in terms of sunlight and cellular respiration uses ATP energy.

Photosynthesis uses energy from the sun and cellular respiration uses glucose to get  ATP energy. Thus option B and D are correct.

what are the factors affecting photosynthesis ?

The process in which autotrophic plants use light energy from sun and convert it into chemical energy, and prepare their food in the form of glucose called as photosynthesis.

This chemical energy is created from water and carbon dioxide and stored as a sugar molecule, it occur in chloroplasts which has three pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.

various factors influence photosynthesis like increase in light intensity causes higher rate of photosynthesis, Higher concentration of carbon dioxide increases the rate of photosynthesis, Temperature range between 25° to 35° C optimum for photosynthesis,

Thus option B and D are correct.

whats the difference between acid , bases and buffers?​

Answers

Please select me as brainiest. It would make my day.

Answer:

A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0. Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ions or OH– ions, thereby maintaining an overall steady pH in the solution.

Why is blood a slightly higher temperature than typical body temperature?
O As bacteria and viruses are destroyed by leukocytes, they release bursts of heat
The bright red pigment of blood warms the internal proteins
O Blood pressure causes formed elements to bump into sides of blood vessels, resulting in friction and resistance
The excess mitochondria in red blood cells produce extra ATP

D. table sugar dissolving in water

Answers

Answer:

Table salt dissolving in water is the example of dissociation.

What do you mean by dissociation?

Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.

Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.

Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.

1. In passive transport, what direction do molecules move?

2. In active transport, what direction do molecules move?

Answers

Answer:

In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.

Explanation:

Passive transport moves molecules from high to low concentration without energy. Energy-driven active transport moves molecules from low to high concentrations.

What is active and passive transport?

The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.

The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

answer the following questions regarding the organism that the product is derived from (reasonable guesses or
speculation is ok):
1. What is the organism?
2. Where does the organism live?
3. Briefly characterize the ecosystem that the organism lives in.
4. Provide one example of how the organism depends on another organism.
5. What are some threats to the organism in the ecosystem?
Speculate on how your life would be affected if the organism became extinct.

Answers

Answer:

1. An organism is a individual animal, plant, or single-celled life form.

2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.

3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.

4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.

5. Pollution(water&air), deforestation, UV Radiation, invasive species.

If an organism went extinct the next generation won't ever be able to see those organisms. If an organism we eat went extinct we would have one less food source which is something that really does not need to happen in today world.
