What is glycolysis?

Back

Glycolysis is the metabolic process that converts glucose into pyruvate, producing a net gain of 2 ATP molecules. It is the first step in cellular respiration.

Front

How many ATP molecules are required to initiate glycolysis?

Back

2 ATP molecules are required to initiate glycolysis.

Front

What is the role of mitosis in multicellular organism development?

Back

Mitosis is the process of cell division that results in two identical daughter cells, allowing for growth and development in multicellular organisms.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for the formation of different tissues and organs.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring, leading to evolutionary changes in populations.

Front

What is an allele?

Back

An allele is a variant form of a gene that can result in different traits or characteristics in an organism.

Front

How do pollutants affect energy transfer in an ecosystem?

Back

Pollutants can reduce the populations of primary producers, leading to less energy being available for higher trophic levels in the ecosystem.

Front

What is the function of transfer RNA (tRNA)?

Back

Transfer RNA (tRNA) delivers amino acids to the ribosome during protein synthesis and then returns to collect more amino acids.

Front

What is the difference between messenger RNA (mRNA) and transfer RNA (tRNA)?

Back

Messenger RNA (mRNA) carries the genetic information from DNA to the ribosome, while transfer RNA (tRNA) brings amino acids to the ribosome for protein synthesis.

Front

What is the significance of benthic microalgae in an aquatic ecosystem?

Back

Benthic microalgae are primary producers that convert sunlight into energy, forming the base of the food web in aquatic ecosystems.
