Answer: The correct answer is a) Peroxisomes.
Explanation: This kind of membrane enclosed organelles has a mainly function that is the oxidation, this source manages to break fatty acids and during normal metabolism, they also has many enzimes like d-aminoacid oxidases, is another of their functions. Further, the catalase enzime (another enzime which is inside peroxisomes) manages the detoxification of chemicals like alcohol from alcoholic drinks (catalases transform the H2O2, which is toxic, into H2O to detoxificate the liver).
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.
Answer:
A landform is a feature on the Earth's surface that is part of the terrain. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons.
When observing the body, there are useful structures that help to locate internal structures. The study between the outside of the body and the structures inside is called gross anatomy.
<h3>What is anatomy?</h3>
- Anatomy describes the structure and location of the different components of an organism to provide a framework for understanding.
- There are two major types of anatomy.
- Gross (macroscopic) anatomy is the study of anatomical structures that can be seen by the eye, such as the external and internal body organs.
- Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.
- Gross anatomy is further divided into 3 fields: Surface anatomy, Regional anatomy and Systemic anatomy
- Within microscopic anatomy, two topics of study are of great importance: Cytology, the study of the structure and function of cells and Histology, the study of the organization and details of biological tissues.
