How do enzymes help to carry out biochemical reactions?A. By decreasing the energy of the reactants
B. By increasing the activation energy of the reaction
C. By decreasing the activation energy of the reaction
D. By increasing the energy of the products of the reaction
E. By decreasing the energy of the products of the reaction

Answers

Answer 1

Answer: The answer is C. Enzymes lower activation energy, allowing the reaction to happen more quickly, which is why they are called catalysts.

Answer 2

Answer:

Answer:

Enzymes help to carry out biochemical reactions C). By decreasing the activation energy of the reaction

Explanation:

Enzyme catalysis An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.

What is aerobic and anaerobic respiration ?

Answers

Aerobic respiration requires oxygen to occur, and then it releases a large amount of energy. Anaerobic respiration occurs when glucose breaks down without any oxygen to produce a little energy, and lactic acid. Anaerobic respiration occurs when we exercise vigorously and the heart and lungs are not able to provide enough oxygen.

Aerobic respiration- the process of respiration which takes place in the presence of oxygen. Glucose breaks and high energy is produced.
Example-normal breathing
Anaerobic respiration- the process of respiration which occurs in the absence of oxygen. Anaerobic respiration generally concludes with less energy
Example- when we run for a long time the lungs and heart do not get enough oxygen and hence we undergo anaerobic respiration
We humans undergo both aerobic and anaerobic respiration

Which feature is found most often in prokaryotic cells?A) plasmid
B) flagella
C) cytoplasm
D) cell membrane

Answers

I would go with the plasmid because the covering is made of it

If we're saying found more often in prokaryotic versus eukaryotic cells, the answer would probably be flagella. Eukaryotic and prokaryotic cells all have cytoplasm and cell membranes at the very least, and its more common in prokaryotic but eukaryotic cells could also have plasmids. Flagella could be occurrent in eukaryotic cells as well, particular in unicellular organisms like protists and even sperm cells, but that feature is probably more common with prokaryotic cells out of all the options in the list.

What is the growth rate? births = 20 deaths = 10 immigration = 5 emigration = 1 25 20 16 14

Answers

Okay let me settle this now... I, just as most of you, hate the giant long explanations, most people are here for the answer, so I'll do us all a favor here... It's 14.

We will write words shortly for the growth rate GR birth B,for death D,for immigration I and for emigration E.
So N=20
D=10
GR1=?
GR1=N-D
GR1=20-10
GR1=10
AND THEN FORM IMIGRATION AND EMIGRATION.
E=125 20 16 14
I=5
GR=?
GR2=E-I
GR2=125 20 16 14-5
GR2=125 20 16 9
AND THEN
GR2-GR1=GR
GR=125 20 16 9-10
GR=125 20 15
I THINK THIS IS THE ANSWER!!!

The role of oxygen in cellular respiration is toa. supply an energy molecule.
b. combine with carbon atoms to form carbon dioxide.
c. allow glycolysis to continue.
d. act as the final electron acceptor. E. aid in the transport of pyruvate into the mitochondria.

Answers

c. allow glycolysis to continue.

The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.

The role of oxygen in cellular respiration is to (d) act as the final electron acceptor. Oxygen is used in all main steps of the cellular respiration; in glycolysis, citric acid cycle, and oxidative phosphorylation. It attracts so much electrons more than any other proteins.

Read and analyze the Ecosystem Response section and list the negative feedback mechanisms that keep the bay ecosystem above its steady state.

Answers

Answer:

Increase occurs in fresh water input.

Decrease occurs in the salinity of the bay.

Explanation:

The low rate of fresh water input and the presence of high amount of salts in water decreases the population of producers such as grasses in bay ecosystem. Due to this decrease, the population of the marine animals decreases due to the low availability of food for herbivorous organism that lives in the bay. The negative feedback mechanisms will be achieved if increase occurs in fresh water input and decrease occurs in the salinity of the bay.
