What is the difference between plants and animals in terms of their biological characteristics and functions?
Plants and animals differ in their biological characteristics and functions. Plants are autotrophic, meaning they produce their own food through photosynthesis, while animals are heterotrophic and must consume other organisms for energy. Plants have cell walls made of cellulose, chlorophyll for photosynthesis, and do not have a nervous system. Animals have complex organ systems, mobility, and a nervous system for responding to stimuli.
Why is energy efficiency of biological systems very low?
Energy efficiency in biological systems is low due to the inherent inefficiency of converting one form of energy to another, such as from chemical to mechanical energy. In addition, biological systems often prioritize other functions, such as growth, reproduction, and maintaining homeostasis, over maximizing energy efficiency. Lastly, evolutionary constraints and trade-offs may limit the optimization of energy efficiency in biological systems.
How do catabolic reactions release energy within biological systems?
Catabolic reactions break down molecules in biological systems, releasing energy stored in the bonds of these molecules. This energy is then used by the cell for various functions such as growth, movement, and maintaining homeostasis.
What functions do membrane proteins serve in biological systems?
Membrane proteins serve various functions in biological systems, including transporting molecules across the cell membrane, acting as receptors for signaling molecules, and providing structural support to the cell membrane. They also play a role in cell adhesion, cell communication, and cell recognition.
Is ATP stable or unstable in biological systems?
ATP is stable in biological systems.

How do the presence of double bonds in fatty acids affect their properties and functions in biological systems?
The presence of double bonds in fatty acids affects their properties and functions in biological systems by increasing their flexibility and reducing their melting point. This allows them to form more fluid membranes in cells and play a role in cell signaling and hormone production.
How does the structure of fructopyranose contribute to its properties and functions in biological systems?
The structure of fructopyranose, a type of sugar molecule, contributes to its properties and functions in biological systems by providing energy for cells and serving as a building block for larger molecules like carbohydrates. The pyranose ring structure of fructopyranose allows it to easily participate in chemical reactions within cells, making it an important source of energy for cellular processes. Additionally, the specific arrangement of atoms in the fructopyranose molecule allows it to interact with other molecules in biological systems, influencing various physiological functions.
When was Journal of Biological Systems created?
Journal of Biological Systems was created in 1993.
