how do enzymes speed up chemical reactions
3 ways
also one of them is lower activation energy and idk what else
Answers
Answer:
Enzymes lower the activation energy of a reaction by...
making the molecules' transition state stableproviding alternate reaction pathwaysdestabilising substratesExplanation:
Enzymes are complex, folded protein structures - in biological processes they facilitate chemical reactions.
Molecules usually collide at random, and specific chemical reactions (breaking and forming bonds) require the correct molecular orientation and energy to react. Enzymes..
provide an alternate reaction pathway with lower energy requirements. stabilize the molecules, keeping them in their transition states til they can react- these usually enter short lived, reactive and high-energydistort the substrate. These slightly alter their typical structures- bonds under stress are easier to manipulate and break, requiring less energy input for changes later onTime and large amounts of energy, are needed to arrive at these orientations to allow the reactions to occur- this is a barrier called activation energy.
Thus, enzymes help by lowering the activation energy needed for the reaction (e.g. hydrolyzing a bond) to progress, and they increase the rate of chemical reactions.

How does cellular respiration work in the human body?
Answers
Answer: Cellular respiration is a process in which your body cells use the oxygen you breathe to get energy from the food you eat.
Explanation: During cellular respiration the cell uses oxygen to break down sugar. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. Carbon dioxide is a byproduct of aerobic respiration in humans.

Cellulose is a type of carbohydrate. Thus option D is correct.
What is cellulose ?
Cellulose is a complex unbranched kind of glucose, a residue polymer formed via beta-1,4 glycosidic connections. It has a chemical formula (C6H10O5)n.
This chiral organic compound is tasteless, odor less, water-soluble and biodegradable.
There are huge application of cellulose in different sectors like paper, textiles, pharmaceuticals, and insulation.
The major classification are monosaccharides which can not be hydrolyzed into simple polyhydroxy aldehydes or ketone units for example glucose, fructose etc.
Oligosaccharides release 2 to 10 monosaccharide units after hydrolysis like Sucrose, maltose.
Polysaccharides are joined by a large number of monosaccharides by glycosidic bond such as starch, cellulose, glycogen.
Three types of major polysaccharides are starch main storage of plants, a polymer of alpha- Glucose and have amylose and amylopectin.
Glycogen are the main storage in animal body and their structure is similar to amylopectin.
Thus option D is correct.

Enzymes involved in the breakdown of fats contribute to the reaction in which way? These enzymes -
O eliminate toxins produced by the reaction.
O increase the speed of the reaction.
O are completely consumed during the reaction.
O reduce the reactants needed for the reaction.
Answers
Answer:
...enzymes increase the speed of the reaction
Explanation:
In biological systems, enzymes are proteins that mediate chemical reactions. They increase the rate of chemical reactions, by lowering the activation energy, required for the reaction (eg. hydrolysing a bond) to occur.
Enzymes require the aid of cofactors, inorganic molecules to act as complements to enzymes. They cause structural changes that result in substrate recognition and binding. Here they act by breaking down large fat molecules into fatty acids and lipids.

Plz help!! We cannot survive without plants, while they would be fine without us. Explain.
Answers
Answer:
We cannot survive without plants because they give us oxygen and food. Plants would be fine without us because the earth gives them everything they need. The sun provides energy; rain, bodies of water, and groundwater provide water; the atmosphere provides nitrogen and carbon dioxide--all of these factors are required for photosynthesis to occur. This is how plants make glucose to feed themselves. Additionally, plants reproduce by several means, whether by pollination or wind spreading seeds to the ground.
Explanation:
Humans cannot survive without plants, while they would be fine without humans because plants produce oxygen.
Photosynthesis:
It is the process in the plant that produces glucose using the Carbon dioxide and water in the presence of sunlight.
During the process plants release Oxygen as byproduct which is used by all animals in the earth.Photosynthetic plants are the only source of Oxygen in the Earth.Plants are the primary producers in the food chain. Hence, consumers will not able to get the food.Humans do not do anything that is compulsive need of plants.
Therefore, humans cannot survive without plants, while they would be fine without humans.
