Some of these steps are reversible and catalyzed by the same enzyme acting in either direction, glycolysis or gluconeogenesis. Which reaction steps are irreversible and require a different enzyme in gluconeogenesis than in glycolysis?

Answer:

Competition, A

Explanation: It's not D mutualism is when animals don't gain a lot or anything from each over. You can think of it as mutual the word.

Example of mutualism: The shark has fish on its back eating up all the dead skin on the shark. The shark gains being clean and the fish gain eating food.

Answer:

D

Explanation:

Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes.

Answer;

There will be formation of products that are (two glucose molecules) simple sugars that joins to make up maltose; and the enzyme would not be affected as one of the property of an enzyme.

Explanation;

Maltase is the enzyme that catalyzes the conversion of maltose to the simple sugars.

Maltose is a disaccharide that is formed by joining two glucose molecules therefore; the action of the enzyme maltase involves breaking it down to form two glucose molecules.

The enzyme is mostly found in plants, bacteria and yeast.

The examples of diffusion/osmosis that occurs in our cells are as follows:

1. O2/CO2 moving in/out of your blood cells as they flow through your lungs
2. H2O moving in and out of all your cells to maintain homeostasis.

DIFFUSION/OSMOSIS:

• Diffusion is the process by which gaseous molecules move from a region of higher concentration to low concentration until they are evenly distributed.

• Osmosis, on the other hand, involves the movement of water from region where it is more concentrated to region where it is less concentrated via a semipermeable membrane.

• Both osmosis and diffusion are forms of passivetransport, meaning that movement occurs down a concentration gradient.

• The following are examples of diffusion/osmosis that occur in human cells:

1. O2/CO2 moving in/out of your blood cells as they flow through your lungs
2. H2O moving in and out of all your cells to maintain homeostasis.

Note that, option B is a form of active transport.
