¬¬¬Biology Exam 4 Energy III – Cellular Respiration (Krebs Cycle and Electron Transport Chain) A. The Krebs Cycle a. Energy i. The net gain of 2 ATP and 2 NADH represents an effective transfer of 20 kcal of energy to ATP (about 10 kcal each) about 80 kcal of energy to NADH (about 40 kcal each)‚ for a total of about 100 kcal ii. Complete oxidation of glucose results in the release of 684 kcal of energy‚ significant energy still remaining in pyruvate b. Eukaryotes i. Pyruvate is transported

Diploid (2n) sporophytes produce spores by meiosis; these grow into haploid (n) gametophytes 2. Gametophytes produce haploid (n) gametes by mitosis; fertilization of gametes produces a sporophyte 3. Angiosperms- sporophyte is dominant generation‚ the large plant * gametophytes are reduced

1. Justify the validity of your model include any limitations of your model. My model is valid because I used reliable sources of information‚ as referenced in my bibliography‚ to find information on what DNA replication looks like. The sources showed me what a strand of DNA looks like as well as giving me an explanation of what occurs during DNA replication. As my model is colour coded it makes it clearer as to what is occurring during each step in DNA replication as well as what each element
Premium DNA DNA replication
Introduction: * Genetics are composed of five main areas: DNA replication‚ meiosis‚ reproduction‚ adaptation and evolution. The body is composed of 46 chromosomes (23 from your mother and 23 of your father). The genes are in your cells in the nucleus and some in the mitochondria. The genes are a small part of a long molecule called DNA. DNA is a double stranded molecule (sugar‚ phosphate and four different bases: Adenine‚ Thymine‚ Cytosine and Guanine). The bases in the DNA are

through a process‚ which was later named recombination. There is one step prior to recombination‚ which is a cross-over event. This event was when‚ “a homologous chromosome wraps itself around another and then exchange genetic information during meiosis” (Larsen 2017‚ pg 54). From this event recombination takes place‚ “the exchange of genetic material between homologous chromosomes‚ resulting from a cross-over event (Larsen 2017‚ pg

What is Life Life is defined as a characteristic that distinguishes that have signaling and self sustaining processes from those that don’t. If an organism can perform certain functions such as movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition‚ it is classified as a living organism. Life began from the basic building block of all living things‚ called cells. All organisms derived from single celled organisms. Cells are the basic building blocks of life and are

DNA is the most important for life One of the most complex and mysterious aspects of contemporary science is the constitution of life. While it goes without saying there are an enormous amount of components that collaborate to achieve the most effective and efficient components of life‚ it’s also clear that some of these molecular components contribute to the actual function of living system more than others. This essay argues the DNA is the most important molecule for life. Deoxyribonucleic
