Researchers have discovered a new membrane protein that has three transmembrane domain αhelixes that span the lipid bilayer. a. If the lipid bilayer is 30 Å thick, what is the smallest number of amino acid residues that can be in each α-helixes for them to be long enough to span the bilayer? b. If one of the three α-helixes is titled at a 32° angle relative to an axis perpendicular to the surface of the lipid bilayer, what is the smaller number of amino acid helixes required for that helix to still span the lipid bilayer? c. How many hydrogen bonding interactions would there be in the smallest possible tilted transmembrane α-helix? d. If the tilted α-helix was a 310 helix instead how many amino acid residues would be required to span the lipid bilayer? How many amino acid residues would be required if it was a π-helix?
Plant Structure and Growth
Roots anchor, the plant, ingest minerals and water, direct water and supplements, and store food. These are two kinds of root frameworks.
Plant Life Cycle
Plants are part of the PLANT KINGDOM, which is one of the five kingdoms of life. Plants are divided into smaller classes based on common characteristics. Certain characteristics are shared by all plants. They are made up of a large number of cells. They also make their own food through a chemical process called photosynthesis, which involves the use of water, carbon dioxide, and solar energy. They pump life-giving oxygen into the air as a by-product.
Life Cycle of Plants
All the organisms that belong to the Kingdom Plantae are known as plants. They are multicellular and eukaryotic and can synthesize their food by photosynthesis, known as autotrophic organisms. They are classified based on certain characteristics, such as the plants bear flowers; some have only naked seeds and do not contain flowers. Some plants neither have seeds nor flowers, such as ferns and mosses.
Plant Morphology and Anatomy
The study of life and organisms is biology. The cell is recognized as the basic unit of life by biology. From ancient Greek, biology is recognized. Modern biology deals with the recent developments in Science.
