What is the role of amino acids in protein synthesis?

Back

Amino acids are the building blocks of proteins. They are linked together in a specific sequence dictated by the genetic code to form proteins, which perform various functions in the body.

Front

What is mutualism in ecology?

Back

Mutualism is a symbiotic relationship between two species where both benefit from the interaction.

Front

How do enzymes function in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a cell plate and in which type of cell is it observed during mitosis?

Back

A cell plate is a structure that forms during cytokinesis in plant cells, such as onion root cells, to separate the two daughter cells.

Front

What does the genotype 'gg' represent in terms of plant color?

Back

The genotype 'gg' represents a yellow plant, as 'g' is the allele for yellow color.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype is the observable physical or biochemical characteristics of that organism.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the significance of the activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur. Lowering this energy increases the rate of the reaction.

Front

What is the difference between mutualism and parasitism?

Back

Mutualism is a relationship where both species benefit, while parasitism is a relationship where one species benefits at the expense of the other.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in plants that absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen during photosynthesis.
