Which of the following best describes the chemical energy that is derived from the krebs cycle? energy is produced in the forms of:

a. atp, which directly supplies energy for many cellular processes, and nad+, which supplies energy for the electron transport chain.
b. nad+, which directly supplies energy for many cellular processes, and atp, which supplies energy for the electron transport chain.
c. atp, which directly supplies energy for many cellular processes, and nadh, which supplies energy for the electron transport chain.
d. nadh, which directly supplies energy for many cellular processes, and atp, which supplies energy for the electron transport chain.

C) ATP, which directly supplies energy for many cellular processes, and NADH, which supplies energy for the electron transport chain

Explanation:

The Krebs Cycle occurs in the mitochondria matrix, and it´s an 8-step cycle, where the last step generates the molecule from the first step (oxaloacetate)

During one cycle, 2 molecules of CO2, 3 of NADH, 1 FADH2 and 1 ATP (or GMP) are generated

This cycle is consider as an aerobic pathway, since both produced  NADH and FADH2 will transfer their electrons to the next pathway in the system , which uses O2

b

explanation:

mitosis

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
