Cell Structure and Types

This section provides a comprehensive overview of cellular components and different cell types. The content explores fundamental structures present in both prokaryotic and eukaryotic cells, along with specialized cell examples.

Definition: Prokaryotic cells are simple organisms without a nucleus, while eukaryotic cells are complex cells containing a nucleus and other membrane-bound organelles.

Example: A bacterial cell represents a prokaryotic cell, while plant and animal cells are eukaryotic.

Highlight: Key cellular components include the nucleus for genetic storage, mitochondria for energy production, and the cell membrane for controlling substance movement.

Vocabulary: Differentiation refers to the process where cells become specialized for particular functions.

Microscopy and Enzyme Function

This section details microscope components and enzyme characteristics. It explains different types of microscopes and their capabilities, along with fundamental concepts about enzyme function and specificity.

Definition: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.

Example: Total magnification calculation: eyepiece lens magnification × objective lens magnification.

Highlight: Electron microscopes offer higher resolution than light microscopes but cannot view living specimens.

Quote: "Enzymes are highly specific, they can only catalyse one reaction."

Enzyme Conditions and Biochemical Testing

This section explores optimal enzyme conditions and various biochemical tests for identifying macromolecules. It details how environmental factors affect enzyme activity and provides specific testing procedures.

Definition: Denaturation occurs when an enzyme's active site changes shape, preventing it from catalyzing reactions.

Example: Benedict's test shows orange-red precipitate for high sugar concentration and green for low concentration.

Highlight: Optimal temperature and pH are crucial for enzyme function; outside these conditions, enzymes denature.

View

Molecular Testing and Calorimetry

This section covers additional biochemical tests and calorimetry procedures for determining food energy content. It provides detailed testing protocols and equipment requirements.

Definition: Calorimetry is the process of measuring energy content in food through heat transfer.

Example: The emulsion test for lipids produces a milky appearance when positive.

Vocabulary: Specific heat capacity is the energy required to raise the temperature of 1kg of a substance by 1°C.

View

Transport Processes

This section explains different cellular transport mechanisms, including diffusion, active transport, and osmosis. It details the movement of particles and water molecules across cell membranes.

Definition: Osmosis is the movement of water molecules from high to low concentration through a partially permeable membrane.

Highlight: Active transport requires energy, while diffusion is a passive process.

Vocabulary: A partially permeable membrane allows some substances to pass through while blocking others.

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.
