Answer:

the correct answer would be C.

Explanation:

it would be C because a hypothesis is your guess of what the results will be. once you test the product you will figure out if your hypotheses was correct or not.

i hope this helps you out!!

Enzymes can accelerate reactions by:___________.

Afina-wow [57]

Answer:

D) lowering the energy for activation.

Explanation:

Just like chemical catalysts that accelerate the rate of chemical reactions, enzymes are biological catalysts that accelerate the rate of biochemical reactions.

Majorly, a catalyst works by lowering the activation energy required for a specific reaction. The lower the activation energy for a reaction, the faster the rate of that particular reaction.

Hence, an enzyme accelerates the rate of reaction by lowering activation energy of the reaction.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c wee

mars1129 [50]

Answer:

Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.

Explanation:

Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.

why is protein synthesis different in prokaryotes and eukaryotes in prokaryotes dna is stored in the cytoplasm in prokaryotes dn

IRINA_888 [86]

In eukaryotes, it exists slowly because the pre- mRNA exists first synthesized in the nucleus and after splicing, the mature mRNA arrives in the cytoplasm for translation.

Therefore, the correct answer is option B. In prokaryotes, DNA is stored in the cytoplasm.

<h3>Why protein synthesis exists different in prokaryotes and eukaryotes? </h3>

The genetic material DNA in prokaryotes forms a cluster in one kind of cytoplasm. This exists named the nucleoid. This exists because they don't contain a well-structured nucleus with a nuclear membrane.

Due to this, the method of transcription in prokaryotes takes place in the cytoplasm, constituting a polycistronic mRNA. This mRNA later experiences translation to contain any number of proteins.

The method of protein synthesis exists faster in prokaryotes as the whole procedure takes place in the cytoplasm.

In eukaryotes, it exists slowly because the pre- mRNA exists first synthesized in the nucleus and after splicing, the mature mRNA arrives in the cytoplasm for translation.

Therefore, the correct answer is option B. In prokaryotes, DNA is stored in the cytoplasm.
