what are the similarities and differences between facilitated diffusion and active transport by a protein pump

Answers

Answer 1

In facilitated diffusion, ions, sugars, and salts are transported across the membrane. In active transport, ions, sugars, and salts are also transported. The second similarity is that both facilitated diffusion and active transport use proteins as their means of transporting their materials to and from the cell.

Answer 2

The similarities between facilitated diffusion and active transport by a protein pump are firstly facilitated diffusion and active transport are two membrane transport mechanisms, which transport molecules across the plasma membrane, secondly transmembrane proteins are involved in both facilitated diffusion and active transport.

The differences between them are facilitated diffusion takes place down the gradient of concentration. active transport takes place toward the gradient of concentration. Facilitated diffusion is a passive method and needs no energy. An active method is an active transport.

What do you understand by facilitated diffusion?

"Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process."

What do you understand by active transport?

"Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy."

What is a protein pump?

"Protein pump– a kind of protein that is capable of pumping out compounds that could pose a threat to the cell."

Lenny accidentally drops his matchbox car into a graduated cylinder. The car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D =
m
v
.
A) 0.5 g/ml
B) 2 g/ml
C) 15 g/ml
D) 50 g/ml

Answers

Answer:

B) = 2 g/mL

Explanation:

Given data:

Mass of car = 10 g

Volume of water = 41 mL

Volume of water+ car = 46 mL

Density of car = ?

Solution:

Density is equal to the mass of object divided by volume of object.

Formula:

d = m/v

volume of car = Volume of water+ car - Volume of water

volume of car = 46 mL - 41 mL

volume of car = 5 mL

d = 10 g/ 5 mL

d = 2 g/mL

-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3

Answers

Answer:

Honey > Water > oil > air

Explanation:

Heavy density will sink and less heavy density will float

So,

Density of honey is highest so, honey will sink

than,

Density of water is higher so, vegetable oil will float

Density of oil is higher so, air will float

Honey > Water > oil > air

When do enzymes stop reacting to the substrates?

Answers

This structure is held together by weak forces between the amino acid molecules in the chain. High temperatures will break these forces. The enzyme, including its active site, will change shape and the substrate no longer fit. The rate of reaction will be affected, or the reaction will stop.

Answer:

If the reaction is divalent metal ion-dependent, you can stop the reaction by adding an excess of EDTA to bind the metal.

You can kill the protein by adding perchloric acid, then precipitate the perchlorate with an equivalent amount of potassium carbonate, leaving nothing but carbonic acid in the supernatant, which bubbles off as carbon dioxide. Centrifuge the sample and take the supernatant to analyze for the product.

A rather slow method is ultrafiltration, using a micro-centrifugal ultrafilter (e.g. Microcon) with a molecular weigh cutoff smaller than the molecular weight of the enzyme. This can be done at 4oC to slow down the reaction during the separation.

What are three ways energy is used by the organisms?

Answers

Answer:

Organisms use energy to survive, grow, respond to stimuli, reproduce

Explanation:

Three ways energy is used by the organism are food, nutrients, and sunlight.

What are living organisms?

Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.

Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.

Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.

Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

Explanation:

Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.
