This creates a dynamic equilibrium in which glucose is both retained and released, allowing a stable amount to be in circulation. Example Question 1 : Understanding Biological Equilibrium Which of following correctly describes how a catalyst affects a chemical reaction? Possible Answers: Has no effect on the speed of the chemical reaction, but increases the amount of product produced Speeds up a chemical reaction by increasing the activation energy Slows down a chemical reaction by lowering the activation energy Slows down a chemical reaction by increasing the activation energy Speeds up a chemical reaction by lowering the activation energy Correct answer: Speeds up a chemical reaction by lowering the activation energy Explanation: A catalyst is a substance that increases the rate of a reaction by lowering the activation energy needed for the given chemical reaction to occur.

Activation energy is the input of energy required for a reaction to occur. This energy is used to break the bonds of the reactant, allowing the reaction to proceed. If a catalyst lowers the amount of energy needed for a reaction to occur, the reaction can occur at a faster rate because it reaches that lower energy level more quickly than it would have the original higher energy level.

GCSE Homeostasis Questions/Answers
Homeostasis requires maintenance of a balance. While ATP production is an essential process, the simple function of the ATP synthase proton pump is not directly related to biological stability in homeostasis. All other answers describe situations in which the body corrects a problem or situation and restores balance to internal mechanisms. This is the nature of homeostasis—there is a disruption to the balance, and the body adjusts in order to keep the processes running smoothly. Example Question 1 : Feedback And Homeostasis Which of the following is an example of negative feedback inhibition? Possible Answers: A cell senses too much sugar in the blood and turns on transcription of the insulin gene A cell senses that the concentration of a protein is too high and represses transcription of the gene encoding the protein A cell senses that there is too little of a protein within a cell and activates transcription of the gene encoding the protein A cells senses too little sugar in the blood and turns on transcription of the glucagon gene Correct answer: A cell senses that the concentration of a protein is too high and represses transcription of the gene encoding the protein Explanation: Negative feedback inhibition occurs when "too much" of a substance results in decreased production of the same or a different substance.

High School Biology : Feedback And Homeostasis
If having too much of a protein in a cell results in decreased transcription of the gene encoding the protein, then the protein was regulated by negative feedback. Another example not listed here would be the presence of too much sugar in the blood and repression of the glucagon gene to reduce production of sugar by other tissues. While insulin and glucagon act in a negative feedback system, the question specifically asks for negative feedback inhibition. Turning on genes for insulin or glucagon would play a role in negative feedback, but would qualify as stimulation rather than inhibition.

Example Question 1 : Understanding Negative Feedback Which of the following is an example of negative feedback? Possible Answers: Ovulation via the luteinizing hormone LH surge Thermoregulation via sweating Childbirth contractions via oxytocin release Blood clotting via fibrin action Lactation via prolactin production Thermoregulation via sweating Explanation: Homeostasis is the tendency of a system to maintain internal equilibrium. As such, negative feedback is a very important component of homeostasis because negative feedback loops are often self-regulating, and are usually very stable. Negative feedback processes result in reduction to change from equilibrium by inhibiting processes that deviate from equilibrium. When body temperature rises, negative feedback through thermoregulation helps to cool the body back to equilibrium temperature.

This is achieved through peripheral vasodilation, increased breathing rate, and sweating. In contrast, positive feedback is when a process reinforces and amplifies deviations from equilibrium. The luteinizing hormone LH surge during ovulation and uterine contractions during child birth are rare examples of positive feedback in biology.

Anatomy And Physiology Questions
Write a paragraph about how an understanding of the human body contributes to person-centred practice. Answer: In writing this paragraph you should have considered the interlink between personhood and anatomy and physiology. For example, understanding how people feel and think is regulated by the nervous and endocrine systems. Understanding how these two systems work is therefore central to those processes. Another example would be in considering the skin. For example, someone with a venous leg ulcer may feel embarrassed and self-conscious about it, feeling unattractive and worried about odour from it. They may decide to avoid social situations, and remain at home more.

This can lower their mood and health-related quality of life. Being able to understand how skin heals can assist the nurse in caring for the wound effectively, which can prevent such a situation or help to resolve it. Briefly describe what is meant by homeostasis. Answer: Homeostasis is regulation of the internal environment in order that a level of consistency is maintained. This is necessary for the cells and organs of the body to operate optimally. Positive and negative feedback systems are used to achieve this. Each cell in the body has a role in maintaining homeostasis. There are a number of resources you can access to read about homeostasis in more detail:.
