What are the main components of a chemical cell?

An electrochemical cell consists of two half-cells. Each half-cell consists of an electrode and an electrolyte. The two half-cells may use the same electrolyte, or they may use different electrolytes.

What is chemical composition in biology?

The body is comprised of different molecules, which, in turn, are made up of elements or compounds. Table of Contents. Atoms. Bonding.

What is cell compound?

Cells are largely composed of compounds that contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organic chemistry and plays a large role in understanding the basic functions of cells.

What is structure of cell?

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

What’s in a cell?

What is a cell? A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.

Why mitochondria are called powerhouse of cell?

Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product.

What is the role of mitochondria in the cell?

The classic role of mitochondria is oxidative phosphorylation, which generates ATP by utilizing the energy released during the oxidation of the food we eat. ATP is used in turn as the primary energy source for most biochemical and physiological processes, such as growth, movement and homeostasis.

What are the three functions of the mitochondria?

The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration and to regulate cellular metabolism.

What types of cells have more mitochondria than others?

The muscle cells has more mitochondria than others.

What sugar is broken down in the mitochondria?

In the cell cytoplasm, glucose is broken down to pyruvate. On entry to the mitochondria, pyruvate is converted to carbon dioxide and water. Its chemical potential energy is transferred to ATP.

Which organ has most mitochondria?

heart muscle cells

What simple sugar is broken down in the mitochondria?

Glucose

What color are mitochondria?

Mitochondria, from liver, concentrated in a pellet are opaque and distinctly yellow in color but when dehydrated and cleared become a transparent red. Submicroscopic particles form a translucent cherry red pellet which when dehydrated and cleared shows a transparent red color deeper than that of the mitochondria.

What do mitochondria mean?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

How does Mitochondria produce energy for the cell answers?

Mitochondria are the powerhouses of the cell because they “burn” or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.

Where is the mitochondria in a cell?

cytoplasm

Is there DNA in the mitochondria?

Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.

What is the Golgi apparatus function?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

What is the structure and function of Golgi apparatus?

The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.

What is a ribosome simple definition?

ribosome. [ rī′bə-sōm′ ] A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum.

What are the three functions of ribosomes?

A ribosome, formed from two subunits locking together, functions to: (1) Translate encoded information from the cell nucleus provided by messenger ribonucleic acid (mRNA), (2) Link together amino acids selected and collected from the cytoplasm by transfer ribonucleic acid (tRNA).

What is the structure and function of the ribosome?

Ribosomes are minute particles consisting of RNA and associated proteins that function to synthesize proteins. Proteins are needed for many cellular functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.

What is the chemical composition of ribosomes?

Ribosomes are made up of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA. In eukaryotes, ribosomes are about half protein and half rRNA.
