Concept explainers
To determine: The main actions of renin-angiotensin-aldosterone pathway.
Introduction: The kidney is an important organ of the excretory system, and nephron is the basic structural unit of kidney. The main function of nephron is ultrafiltration. It removes waste products, ions, and excess water from the blood, and returns the required molecules back to the blood. The glomerular filtration rate (GFR) refers to the rate of flow of filtered fluid through the kidney.
To compare: The main actions of this pathway with the actions of atrial natriuretic peptide (ANP).
Introduction: Blood pressure is the force that moves the blood through the circulatory system. Angiotensin, antidiuretic hormone, aldosterone, and atrial natriuretic peptide are hormones that participate in regulating the blood pressure.

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…arrow_forward
