What are three similarities between photosynthesis and respiration?

1 answer:

7 0

Ellular Respiration and Photosynthesis both have an ATP Synthase. These processes both have buildups of H+ and the ATP Synthase transports the hydrogen ions down the concentration gradient. This process is called Chemiosmosis.
Similarities between Photosynthesis and Cellular Respiration.
Cellular Respiration and Photosynthesis are both metabolic pathways. This means that the products created in Cellular Respiration are the reactants in Photosynthesis. While the products created in Photosynthesis are the reactants in Cellular Respiration. They are also metabolic pathways within themselves. In Photosynthesis, the products from the first phase (NADPH and ATP) are used in the second phase of Photosynthesis as a source of energy. In Cellular Respiration some products of glycolysis, intermediate step, Krebs Cycle are the reactants in Oxidation Phosphorylation.

Answer:

1. C

2. I

3. B

4. I

5. A

Explanation:

1. Nonrenewable resources include oil, natural gas, coal, and nuclear energy.

2. Nonrenewable resources cannot be readily replaced at the speed with which they are being consumed.

3. Renewable sources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, etc.

4. Because they take a very long time to form. They are not replaceable.

5. Corn can be used for ethanol fuel, and a new crop of corn can be grown and harvested each year. Corn is a renewable resource. Also, renewable resources cannot be replaced in our lifetime.

most people don't need to count every single micronutrient they eat. instead doctors recommend that they eat a well balanced die

Answer:

The nutrition therapy goals for the individual with diabetes have evolved and have become more flexible and patient centered. The goals from the American Diabetes Association (ADA) 2019 include the following: (2)

To promote and support healthful eating patterns, emphasizing a variety of nutrient dense foods in appropriate portion sizes in order to improve overall health and:

➢

Achieve and maintain body weight goals

➢

Attain individualized glycemic, blood pressure, and lipid goals

➢

Delay or prevent complications of diabetes

To address individual nutrition needs based on personal and cultural preferences, health literacy and numeracy, access to healthful food choices, willingness and ability to make behavioral changes, as well as barriers to change

To maintain the pleasure of eating by providing nonjudgmental messages about food choices

To provide an individual with diabetes the practical tools for day-to-day meal planning rather than focusing on individual macronutrients, micronutrients or single foods

The American Association of Clinical Endocrinologists (AACE) guidelines have similar goals for people with type 2 diabetes. (3)

Describe the process of light-independent

xxTIMURxx [149]

Explanation:

Light energy is absorbed and transferred to the reaction center.
A water molecule is split.
Electrons are transferred from photosystem II to photosystem I.
ATP is synthesized from ADP and inorganic phosphate.

Output: ATP, NADPH, O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
the electron moves down an electron transport chain (to PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
ATP synthase converts ADP and Pi to the energy storage molecule ATP.
The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
