Liuyi Bian P2 1. The physical structure of a protein often reflects and affects its function. (a) Describe THREE types of chemical bonds/interactions found in proteins. For each type‚ describe its role in determining protein structure. Different types of bonds/interactions in proteins lead to different kinds of structures. Three of the most commonly known chemical bonds in proteins include the hydrogen bond‚ the covalent bond‚ and the ionic bond. In hydrogen bonds‚ hydrogen interacts with

A. C4 and CAM plants are plants that use certain special compounds to gather carbon dioxide (CO 2 ) during photosynthesis. Using these compounds allows these plants to extract more CO 2 from a given amount of air‚ helping them prevent water loss in dry climates. CAM and C4 plants are similar with the exception that CAM only opens up the stomata’s at night. They both photosynthesis at the same rate for the majority at a time and are tolerate to heat. Plus C4 closes their stomata’s during hot

There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

wildlife? We must make a conscious effort to conserve the world’s plants and animals. Plants are essential for our own survival. Plants use the sun’s energy to make food—a process called photosynthesis. Therefore plants are the first important link in the food chain of which humans also form a part. During photosynthesis‚ oxygen is released and oxygen is vital for the existence of life itself. Animals need plants in order to survive‚ but plants also need animals. Animals and plants are therefore

The control stays the same and a variable is tested during an experiment. 7) What is the purpose of writing a conclusion in a lab report? The purpose of a conclusion in science is to sum up your results‚ your purpose‚ and your errors. 8) What can you use to put your collected data into so it is easy to read? In a graph or chart. 9) What piece of equipment measures mass? Triple

or even stops. Plants are able to control the whether their stomata are opened or closed with the use of guard cells‚ which surround the stomata. Plants open their stomata only when light intensity is sufficient to maintain a moderate rate of photosynthesis. Therefore they generally keep their stomata closed at night because no CO2 is need at night (Sadava et al.‚ 2009). 3. Many abiotic factors can affect transpiration rate. List these factors‚ and talk more specifically about the ones we tested

currently consists of approximately 0.04% of Carbon dioxide. A large proportion of it is found dissolved in the oceans as well as the atmosphere. The carbon cycle consists of 6 stages. Initially the CO2 that is absorbed by plants for the use in photosynthesis becomes carbon compounds in plant tissue. The carbon is moved up the food chain by consumption‚ a primary consumer. It is passed on to the secondary and tertiary consumers when they eat other consumers. When these organisms die they are digested
