Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+. A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA. The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.

Photosynthesis occurs in photosynthetic ____ localized in large organelles known as ____. a. membranes; chloroplasts b. proteins

Aleks [24]

Answer:

The correct answer is option a. Membranes; chloroplast.

Explanation:

Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.

This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.

Thus, the correct answer is option a. Membranes and chloroplast

Answer:

Some species are similar in structure because they are evolved from the same ancestors while some differences are also present in them due to the changes occurs in the body because of adaptation to environmental conditions.

Grizzly bears and sea otters have canine teeth because canine teeth are used to crushing hard food materials such as fishes and shells.
