Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in both autotrophs and heterotrophs.

Front

Which organisms perform cellular respiration?

Back

Both autotrophs and heterotrophs perform cellular respiration.

Front

What happens to enzymes when they are heated to a high temperature?

Back

Enzymes can become denatured, meaning their shapes are altered, which affects their ability to function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where the three-dimensional structure of an enzyme is altered, usually due to heat or pH changes, rendering it inactive.

Front

What is the site of protein synthesis in a cell?

Back

The ribosome is the site of protein synthesis in a cell.

Front

What is a byproduct of the light-dependent reactions of photosynthesis?

Back

Oxygen is a byproduct of the light-dependent reactions of photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the role of ribosomes in cells?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain energy by consuming other organisms.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions in the body without being consumed in the process.
