Basics of Cells and Enzymes

Question 1

Enzymes

Think of an annotated diagram of the lock-and-key model

Answer 1

Question 2

Enzymes

Explain the induced-fit model

Answer 2

The induced fit model describes how enzymes become more affective at catalyzing reactions by changing their shape to better fit the substrate.

Question 3

Enzymes

Explain why a change in an enzymes shape causes it to denature

Answer 3

A change in an enzyme’s shape causes it to denature because its specific three-dimensional structure is crucial for its function.

The shape determines the enzyme’s active site, where substrate molecules bind and undergo a chemical reaction. When the shape changes, often due to factors like temperature, pH, or chemicals, the active site can no longer bind substrates effectively, leading to a loss of enzymatic activity.

Question 4

Basics of cells

What are prokaryotes and eukaryotes?

Answer 4

Prokaryotes are an organism with no membrain bound organelles and eukaryotes have membreain bound organelles.

Question 5

Basics of cells

What is endosymbiosis?

Answer 5

Endosymbiosis is a relationship where one organism lives inside another. It explains how mitochondria and chloroplasts in eukaryotic cells originated from free-living prokaryotes that were engulfed by a host cell, eventually evolving into essential organelles.
