nonphotosynthetic animals‚ and the carbohydrates (and other biomolecules) can be broken down and used for cellular respiration. As we ourselves are non-photosynthetic organisms‚ we must obtain our energy through what we ingest‚ i.e. via our diet‚ so that our cells are able to carry out all the necessary biochemical reactions. The amount of energy required by an individual will depend on the amount of physical activity they perform‚ but in general an average man requires about 10 500 kilojoules (kJ)‚ equating

I have studied a variety of subjects such as animal biology‚ genetics‚ comparative vertebrate anatomy‚ immunology‚ plant biology‚ biochemistry‚ and animal behavior. I have been challenged in new ways to think‚ when I fail I seek to find new approaches to solutions and remain persistent. Biochemistry was a very difficult course‚ with may cycles and chemical processes that are very precise and intricate. By repeated drawing of each step I was able to remember and

Eukaryotic Cell Division Cells must continually grow and divide in order for an organism to grow‚ maintain its structure‚ and reproduce. Cell division involves the replication‚ or copying‚ of the complete set of hereditary information. It also involves the equal distribution of the genetic material in the resulting cells. The hereditary information of organisms is contained in large molecules called deoxyribonucleic acid‚ DNA. Objectives Upon completion of this laboratory

potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction). Voltaic cell is a device in which a

GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the heart)‚ the

observations are repressentative of cell division taking place in the oinon root tip. Firstly‚ this is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups‚ so we can assume our results are most likely correct. We can also assume our calculations are right because we know that Interphase is the most active phase in the process of cell divison‚ which would agree with our calculations since we assume that approxiamtly 93% of cells are going though Interphase

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound

fermentation of human beings is the simplest type of fermentation for which is a typical redox reaction. In anaerobic conditions‚ the primary mechanism of ATP production of a cell is glycolysis. Glycolysis will transfer electron (reduction) to NAD+‚ forming NADH. However‚ during lactic acid fermentation‚ the supply of NAD+ is limited in a cell. For glycolysis to continue‚ NADH must be oxidized (gives away electron) to regenerate the NAD+. This is done through an electron transport chain in oxidative phosphorylation
