The cytoplasm is also where nutrients are absorbed and processed and is where many chemical reactions take place. Cytoplasm This is a semi-fluid material likened to a gel. It holds together the organelles, apart from the nucleus of the cell and supports the cells structure to make it possible for molecules to be transported. The cytoplasm is also where nutrients are absorbed and processed and is where many chemical reactions take place. Mitochondrion Mitochondria are concerned with energy release.
Rough ER transports these proteins to the regions in the cell where it is needed. | Ribosomes | A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. | the main thing they do is that they arrange the strands of the amino acids for use of the other parts of the cell and ultimately the body. | Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER.
To turn light into energy. • Because photosynthesis only occurs in plants, why is it essential to animal life? Animals eat plants to make energy; also plants make oxygen as a bi-product of photosynthesis. • What is the role of the light reactions? Include the reactants and the products.
Cytoplasm is located within the cell membrane and all cell types and contains all organelles and cell parts. Majority of all the important activities take place in the cytoplasm as cytoplasm consist of enzymes which are responsible for breaking down waste and also aid in metabolic activity. Nucleus: The nucleus is the control system of the cell. The nucleus contains the DNA of the cell. The function of the cell is to maintain the integrity of these genes and to control the activities of the cell by regulating the gene expression.
In this task I will outline the functions of the main cell components. Which consists of the Cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum (smooth and rough), golgi apparatus and lysosome. Cells are the structural and functional units of all living organisms. Cells can take in nutrients, change these nutrients into energy and can carry out particular functions, and reproduce them if needed. Mitochondria Mitochondria Nucleus Nucleus Lysosome Lysosome Golgi apparatus Golgi apparatus Cell membrane Cell membrane Endoplasmic reticulum (Smooth and rough) Endoplasmic reticulum (Smooth and rough) Cytoplasm Cytoplasm Cell Membrane A cell membrane of the cell.
* ATP What is meant by phosphorylation? What does it cause? * Phosphorylation is the addition of a phosphate (PO43-) group to a protein or other organic molecule. Phosphorylation turns many protein enzymes on and off, thereby altering their function and activity. Protein phosphorylation is one type of post-translational modification.
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
| Smooth Endoplasmic reticulum | "Smooth" indicates that there are no ribosomes attached to the surfaces of the endoplasmic reticulum. The endoplasmic reticulum is where proteins and lipids are produced within the cell, and is also concerned with the transport of these materials within the cell. | Lysosome | Lysosomes are tiny sacs filled with enzymes that enable the cell to utilize its nutrients. Lysosomes also destroy the cell after it has died, though there are some circumstances (diseases/conditions) in which lysosomes begin to 'break-down' living cells. | Nucleolus | The nucleolus is responsible for the cell organelles (e.g.
According to Hopkins (2006), photosynthesis is the process by which green plants and certain organisms transform itself from light energy into chemical energy. As a straight forward chemical reaction in which carbon dioxide comes from the air, along with the midair and water from the soil, photosynthesis conglomerates to produce what is known as carbohydrate (p. 6). Solar Energy produced by photosynthesis, stores itself in a chemical bond of a carbohydrate molecule. Sugar known as glucose is then formed which becomes convenient both by way of energy to be stored for later use in tissues or by way of carbon to be used for cells (p.7). Hopkins, w. G. (2006).
