in which direction do particles in a solution move during passive transport

Answers

Answer 1

During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.

What is the importance of the different types of transportation?

In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.

Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.

Which of these statements concerning lipids is not true?

A. Lipids are substances that dissolve in nonpolar solvents.
B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.
C. Fats, phospholipids, and steroids are lipids.
D. The building blocks of fats (triglycerides) are fatty acids and glycerol. ​

Answers

Answer:

B

Explanation:

Unsaturated fatty acids have double bonds. Fatty acids that contain only single covalent bonds between the carbon atoms are called saturated.

The statement: "B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated." is NOT TRUE.

Lipids include the following group of compounds:

FatsOilsPhospholipids SteroidsWaxes

The above compounds are nonpolar hydrocarbon compounds that are insoluble in water. This means they can hardly dissolve in water.

Fatty acids, which is an example of lipids, can either be saturated or unsaturated. If it is saturated, it means they contain only single covalent bond among the carbon atoms while it is unsaturated if a double bond exist in the chain of the molecule.

A fatty acid that contains only single covalent bonds cannot be called "unsaturated." It is rather "saturated."

Therefore, the statement concerning lipids that is not true is: B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.

An example of a saturated fatty acid is shown in the attachment below:

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?

Answers

Answer:

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.

Explanation:

Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.

The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.

Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.

What are two ways in which cells use the energy temporarily stored in ATP?

Answers

Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways

The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.

What is Active transport?

Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.

ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.
