Biology Review 1

Front

Where in the cell does cell respiration occur?

Back

Mitochondria: The organelle where cellular respiration takes place, converting glucose and oxygen into energy (ATP).

Front

What type of organic molecule are enzymes, hemoglobin, and maltase?

Back

Proteins: Large, complex molecules that play many critical roles in the body, including catalyzing biochemical reactions.

Front

What happens to a freshwater cell placed in a saltwater solution?

Back

Shrinks: The cell loses water to the surrounding saltwater due to osmosis.

Front

What is a requirement of Natural Selection?

Back

Reproduce: Living organisms must be able to reproduce to pass on their traits to the next generation.

Front

How do enzymes affect Activation Energy?

Back

Decreasing: Enzymes lower the activation energy required for a reaction to occur.

Front

What is the function of chloroplasts in plant cells?

Back

Photosynthesis: Chloroplasts convert sunlight into chemical energy through photosynthesis.

Front

What is the primary function of the cell membrane?

Back

Regulation: The cell membrane controls what enters and exits the cell, maintaining homeostasis.

Front

Define osmosis in biological terms.

Back

Osmosis: The movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of DNA in cells?

Back

Genetic Information: DNA contains the instructions for the development, functioning, growth, and reproduction of all known living organisms.

Front

What are the building blocks of proteins?

Back

Amino Acids: Organic compounds that combine to form proteins, essential for various biological functions.
