What Is A Cell?

Cell Definition. "A cell is defined as the smallest, basic unit of life that is responsible for all of life''s processes.". Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life .

Introduction to cellular respiration and redox

Cells need energy for all kinds of things: moving things around, producing substances, getting nutrients, etc. For cells, this energy typically comes in the form of a molecule called ATP. Cellular respiration is a series of steps by which fuel molecules (such as glucose from your food) can be used to produce ATP that the cell can use.

4.1: Cell Structure and Function

The plasma (cell) membrane separates the inner environment of a cell from the extracellular fluid. It is composed of a fluid phospholipid bilayer (two layers of phospholipids) as shown in figure 4.1.2 4.1. 2 below, and other molecules. Not many substances can cross the phospholipid bilayer, so it serves to separate the inside of the cell from ...

Chapter 6. Cell Structure and Function

Learning Objectives. At the end of this unit, you should be able to: I. Specify the characteristics associated with life and explain why the cell is the basic unit of life. II. Describe the levels of structural organization in the body. III. Describe the structure and the functions of the major components of a cell. IV.

Cell (biology)

The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin …

4.1: Energy and Metabolism

Enzymes are important for catalyzing all types of biological reactions—those that require energy as well as those that release energy. Figure 4.1.2 4.1. 2: Catabolic pathways are those that generate energy by breaking down larger molecules. Anabolic pathways are those that require energy to synthesize larger molecules.

Adenosine Triphosphate (ATP)

Adenosine Triphosphate Definition. Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and …

Mitochondrion | Definition, Function, Structure, & Facts | Britannica

mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP). Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm.
