Biology Spiral Review HW Week 27

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance. Its removal can lead to significant changes in the ecosystem.

Front

What happens to biodiversity when a keystone species is removed?

Back

The removal of a keystone species can lead to a decrease in biodiversity and potentially the collapse of the ecosystem.

Front

What is ATP and its role in biological processes?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells, playing a crucial role in metabolism and energy transfer.

Front

What is the impact of human activities on ecosystems?

Back

Human activities, such as farming and urban development, can lead to habitat destruction, resulting in less biodiversity.

Front

What is the optimum temperature for enzyme activity?

Back

The optimum temperature for enzyme activity is the temperature at which the enzyme functions most efficiently, often around 30°C for many enzymes.

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.

Front

How do enzymes affect biochemical reactions?

Back

Enzymes lower the activation energy required for biochemical reactions, allowing them to occur more quickly and efficiently.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their relative abundance.

Front

What is the relationship between biodiversity and ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, as diverse ecosystems are more resilient to changes and disturbances.

Front

What is a biochemical process?

Back

A biochemical process is a chemical reaction that occurs within living organisms, involving biomolecules such as proteins, nucleic acids, and carbohydrates.
