Explain how concentration gradients across membranes are maintained

Biology
1 answer:
puteri [66]3 years ago
8 0

Answer:  

The idea of concentrations and gradients within them is important when understanding the movement of substances across cell membranes. The more particles there are in a certain volume, the more concentrated those particles are. A solution with a low solute concentration has a high water concentration, and a high water potential.

Which of the following organelles is primarily responsible for the formation of the cell's lysosomes
Marizza181 [45]
<h3><u>Answer;</u></h3>

Golgi apparatus or Golgi complex or Golgi bodies

<h3><u>Explanation;</u></h3>
  • <u><em>Golgi apparatus are also called Golgi bodies or Golgi complex. They are complex vesicles and folded membrane within the cytoplasm of eukaryotic cells.</em></u>
  • <em><u>Golgi apparatus are important in the secretion and intracellular transport roles. A major function is the modifying, sorting and packaging of proteins for secretion. T</u></em><em><u>hey are also involved in the transport of lipids around the cell, and the creation of lysosomes.</u></em>
  • Therefore, <u><em>Golgi apparatus are the organelles responsible for the formation of lysosomes, which are organelles that destroy old and worn out cellular organelles. </em></u>

Anuta_ua [19.1K]

Answer

          The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become <u>utilize</u> in the last one.

Explanation

         Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.

Aerobic respiration complete in four main steps:

1. Glycolysis

                  In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.

2. Oxidation of pyruvate

                In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A.  Again 2NADH are formed in this step.

3. Kreb Cycle

            It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.

4. Electron transport chain

            All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.

The chemical energy of these plants all started with what energy source?
Zielflug [23.3K]

Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

  • green plants manufactures their food using sunlight.
  • in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.
