The citric acid cycle is the second step of cellular respiration also known as the Krebs cycle. By the end of this reaction 2 atp will have been formed.
One: The cell is able to move material in and out of the cell
Two: It helps the cell maintain necessary conditions for life
The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.
The four types of tissues are:
. The epithelial tissue
. The connective tissue
. Muscle tissue
. The nervous tissue
. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.
. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.
. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.
. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.
Answer:
Within the extracellular fluid, the major cation is sodium and the major anion is chloride.
Chloride is a major contributor to the osmotic pressure gradient between the ICF and ECF, and plays an important role in maintaining proper hydration. It functions to balance cations in the ECF, maintaining the electrical neutrality of this fluid.
Chloride is by large the major anion in the extracellular fluid.
Its concentration in blood plasma is around 98.00–107.00 (mM), in cerebrospinal fluid (CSF) around 118.00–132.00 (mM) and in urine around 110.00–250.00 (mM); while the concentrations of bicarbonate (HCO3-), the second most abundant anion in blood is 22.00–29.00 (mM).
Chloride is the predominant extracellular anion. Chloride is a major contributor to the osmotic pressure gradient between the ICF and ECF, and plays an important role in maintaining proper hydration. Chloride functions to balance cations in the ECF, maintaining the electrical neutrality of this fluid.
*ICF = intracellular fluid
ECF = extracellular fluid
The answer is B. Periosteum
