Passive transport involves movement of substances

Biology
1 answer:
gtnhenbr [62]3 years ago
5 0

Answer:

Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.

Explanation:

Passive transport involves the passage of substances through a semi-permeable membrane, as occurs with transport at the level of cell membranes.

Generally, passive transport occurs with the <u>movement of compounds from the space with the highest concentration of a specific substance to the space with the lowest concentration of the same substance</u>, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.

Regarding other options:

<em>     A. </em><u><em>From areas of lower concentration to areas of higher concentration</em></u><em>.  It is a feature of active transport.</em>

<em>      C. </em><u><em>From areas in which the concentration has reached a balance</em></u><em>.  There is no passive transport</em>

<em>      D. </em><u><em>From areas of differing concentrations with the use of cellular energy</em></u><em>.  Energy use involves active transport.</em>

Enzymes are proteins so why don't proteins break themselves down? (Why are enzymes needed?)
vampirchik [111]

Explanation:

Enzymes are biological catalysts. They speed up the rate of reaction (without themselves being chemically changed at the end of reactions) Enzymes only speeds up the rate of reactions they don't break down stuff

in addition, proteins are broken down in chemical reactions. enzymes being proteins of course will get broken down as well but they do not break themselves down since they never will break anything down

enzymes are needed as they lower activation energy (activation energy is often supplied in the form of heat but for some reactions to take place, the heat energy required may be too hot for a body to handle (such as a human body) this will cause negative effects to the reactants and the body. as a result, enzymes are the ones who help to reduce such happenings) and speed up rate of chemical reactions. by lowering activation energy, less heat is needed to be supplied to the reactants for them to react and hence less energy is required (aka in most cases less heat is required)

hope that gives you a better understanding on enzymes :)

aleksley [76]
<span>The synthetic estrogen-like hormone is classified as a xenohormone. Xenohormones have hormone like affects when absorbed or ingested by animals. As a result, they cause a variety endocrine complications. These types of compounds in the environment can easily find their way into the fishes that humans consume and eventually cause endocrine problems in the human population.</span>

In 3-5 sentences, construct a summary of the process of gene expression, starting with DNA and ending with proteins.
sveta [45]

The mechanism of gene expression initiates with the process of transcription in which the genetic information in the DNA is into genetic codes in the form of messenger RNA.

<h3>What is the process of gene expression followed by transcription?</h3>

The process of gene expression followed by transcription is processed through the messenger RNA which then undergoes some processing such as modification of tails and removal of non-coding sequences before the genetic codes are translated to their respective amino acids in a process known as translation.

The amino acids are typically associated together by peptide bonds and the resulting primary protein structure is folded in specific ways depending on their functions.

when a tall plant is crossed with a short plant some of the offspring are short. what are the genotypes of the parents?
o-na [289]

If the tall plant is heterozygous (T,t) the genotypes would be Tt,Tt,tt,tt.

If the tall plant is homozygous (T,T) the genotypes would be Tt,Tt,Tt,Tt.

hope that helps :)
